Ive used etap for 3 years and its worked flawlessly, never dropped a chain even on a 1x with a standard clutchless rear derailleur, but what really sells it to me compared to Shimano is that you don't have to run a wire through the frame.
I'm interested to see what the new (2021?) Dura Ace spec will look and feel like. Wireless, some weight savings here and there, improved drivetrain performance (once again). I race on SRAM and love it, but cannot deny the overall powerhouse package that Dura Ace offers.
Imo shimano just simply does a better job. Only down side it has wires that u need to feed through your frameset once 😂. Fact is sram seems to drop chains a lot so much so sram make a chain catcher for this very issue... Ever since riding di2 I've never suffered with a chain dropping. Also imo I prefer 1 battery over 4 batteries (1 in each hood and 1 on each mech) Each to their own but only thing I like about sram is a cleaner look. In terms of proformance and reliability shimano di2 everytime.
DC _Cycling people act as if „performance“ differences were relevant to their riding. Ronald Kuba claims, that there is 5W in a Shimano specific race chain over a SRAM specific race chain at 300W. Don’t know if that’s true or not, but it clearly doesn’t matter to most people. I had my chain drop twice over the best 15000km. Once on a SRAM Red AXS and Once on a Shimano Ultegra Di2. Don’t really know what to make of that.
That just means you didn't set it up correctly. I have been riding my Red AXS all year long and haven't dropped the chain once. But then again, I did set it up myself.
I was a sram fan but not happy with where they are going. Dura ace groupset is also much lighter which is mad as sram was always known for being the lightest groupsets. Who ever is in charge of sram should be fired!
Ronald Kuba what I am saying is that they had a usp of light weight and top Quality and efficiency, and they have thrown it away. They do not do any mechanical groupsets anymore, and you can’t choose your own chain ring or power meter on axs red. Not to mention the high friction and load on that 10 tooth cog which will have more watts lost.
Nic Eracleous with Power Meter and Dub, a Shimano Dura Ace Di2 is 140g lighter than SRAM Red AXS, and you get one more gear. It’s not that much of a saving.
Lars sram axs red is 300g heaver the dura ace now. If that was off the frame, that would be the difference of thousands of pounds. That’s a lot in bike world. It was the other way around, And you get one extra gear which is notch and wears out really quickly
I took delivery of a new bike with dura ace di2 4 weeks ago which is also available with SRAM etap axs. Together with the bike shop we have been struggling from the beginning to get rid of chain noise. We managed to have the noise greatly reduced but it is still there albeit faint but it irritates me and takes away the my enjoyment of an otherwise great bike. I still have the option to trade in for SRAM but I am not encouraged by this video and comments. Anybody else having this issue with Shimano (dura ace di2) or knows how to resolve it ?
I had exactly the same issue, although with Ultegra Di2. Drove me insane. Ended up selling the bike in the end. Now riding SRAM red Etap axs and it is almost totally silent (apart from when shifting of course). I can’t hear it at all when pedalling. Amazing in this regard. Also prefer the sram shifters, particularly in winter, and the batteries, and the look. Had a few chain drop issues but as Ronald has pointed out that is almost certainly down to set up. Hope this helps.
From where did you get the "special" chain? Is it available to the public? How much faster is it compared to a molten speed wax treated chain? Thanks a lot for your great insights!
Hi Ronald, can i please ask ur experience with sram etap 11s regarding der xg1190 cassette, is it as noisy as some may have suggested in various cycling fourms?? I'm awaiting delivery on 11-30 xg1190 cassette and red 22 chain. Greetings from Ireland 🇮🇪
Hey Ronnie, I see you stopped putting bar tape pieces on top of your aerobars to get in the TT position on road bike. Have you found another solution to make sure you can hold that position solidly? I ride a foil (the old cockpit) and especially with long sleeves it's very tricky to ride elbows on handlebars.
do you still use that Absolute Black chain? and do you wax that graphene lube chain with the Molten Speed Wax? what's your current chain/lube setup of choice?
i have eTap on my TT bike for simplicity. i've ridden di2 and would choose di2 for performance all day over eTap (like on a road bike). but since i shift sparingly on the TT bike, eTap is OK. i have had chain drops with eTap and so if going 1x I would highly suggest a chain catcher.
@@ronykuba Interestingly, SRAM have also just released an 11 speed eTap rear derailleur with an AXS-style clutch in it too. I'm interested to know why you didn't choose an Ultegra RX RD for the TT bike. Would have made more sense for the 1x set up... but yeah no Dura Ace logo...

@@ronykuba, Thanks , I appreciate you taking the time to reply. The industry figured out how to make chains more then a century ago.

A 1.7% efficiency improvement, between two market leading companies, by a none obvious different chain design seems like an lot. I dont accept it on face value.
Di2 shifting action at the levers is actually more similar to sram mechanical. Fixed, non-swinging levers with shifter paddles behind. The swinging shimano levers were what made me like SRAM mechanical more originally

Among Sram different groupsets, which one stands higher and better, speacially for a road climbing bike? Or you prefere Shimano for where most of your ride is in a concrete road with steepy hills
Hi. Thanks for your videos. I see in your other video you have xx1 AXS on your MTB. My question is, do you think xtr di2 is better than xx1 AXS for MTB? Also I came across an article suggesting xx1 AXS + xtr cogs and chain would be "mismatch made in heaven". Would like to know your thoughts on this. Cheers.
XTR di2 is hopelessly outdated, although it uses the same chain as Dura Ace. For XX1 there are efficient chain options, I don't think mismatching stuff would make much sense.
I agree axs flattop chains are very limiting. One idea I am considering is to changebto regular 11 speed chain, change the cassette and chain ring to suit..... And reprogram the axs groupset to work to 11 speed. Mind you the derailleur pullrys may need to be changes too.... As spacing of axs chain Rollers are different. Just a thought.... Haven't tried that yet but I believe that would be a hack without having to change over entire group set.
Thank you for sharing the difference in efficiency between SRAM and Shimano’s. Do you know of any published findings to support the claim? I am unable to find anything to support the claim on the internet. 5 Watts is a big difference indeed.
Rony, I did the same thing. I've been a loyal eTap user for 2+ years. It is just so simple to install and the brake bleeding for the HRD version is better in my opinion. I think wireless is great and being able to take out the batteries easily is great for those of us who travel with bikes. I got a new bike with Shimano Di2 and within one ride, I was smitten. The shifting is better and 1000 miles later- no chain drops. The shifting works fantastic- even with low rpm. I use a 53/36 and 11-30 and this works great for me in the SF Bay Area. The drawbacks for Shimano for me are the inconsistencies in the power meter readings from the r9100 (GPLama has a great bit on this) and the connection dropouts with the bluetooth unit.
Hi Ranold, I'm using sram red axs 1X 50T, 10-33T and I just bought 60T front chainring. Do you know sram red flattop chain long enough for this 60T chainring?
But there are a few world tour teams that are not sponsored by Shimano like Astana or Israel start up nation and no team without a groupset sponsor uses SRAM or Campagno.
AndreasHappyfarm Shiv TT 2020 1X SRAM Red AXS, 2020 S-Works Roubaix Team Edition SRAM Red AXS 2X, 2019 Cervelo S5 Disc SRAM Red AXS 2x, Open WI.DE SRAM Force/XX1 AXS Mullet. All of the work perfectly.
@@LarsRR Yes it works fine, but not with the speed of Shimano. I really like my XX1 AXS stuff. But riding Force back to back with Di2 makes the deficiency pretty obvious. Everyone I know that rides both feels the same way. Shimano brakes better, shifts faster, weighs less, makes less noise and is better made.
Ronald, I really appreciate your neutrality and keeping an open mind to experiment. Agree on the "fanboyism" - it's just pros/cons that are highly subjective to a rider's use-case. BTW - Quick question: Any thoughts on the Kogel OSPW? They claim to have a stiffer cage than Cermaicspeed to improve shift performance.
@@benbisson9608 i myself didnt like syncroshift because i like to be in the 53 chainring as long as possible during races. found it frustrating during training, and went manual. Power transfer feels better on the big ring and changing from small to big ring on top of the climb just takes an extra second or two.
@@benbisson9608 I used semi synchro for a bit. And then I just go back to manual. Even compensation rear shift when I shift the front is not always required. So I'd rather have full manual control.
Respectfully. Summer of 2019 after receiving my near first issue Red AXS and soon after completed the California Death Ride 120 miles 15k climbing all in the altitude of the Sierras in 6.5 hrs and then this year road the route of Colorado’s Triple By-Pass 120 miles and 10k of climbing all in the altitude with a couple of friends all with zero issues. All aboard my Moots Routt RSL. This group is sublime. Easy to use and bullet truly proof. SRAM has truly set the bar IMHO and continues to evolve. Batteries clicked out of their cradles and charged versus moving your entire bike over to attach a charging cable to an outlet. On road change of batteries is so easy, front to rear, rear to front, no problem. All charging diagnostics read from your phone, easy. Shimano, always a juggernaut seems to be in a holding pattern at the moment. No substantial enhancements or streamlining. Not sure why but I’m sure there’s something on the horizon in that camp. You can count on it. Competition makes for the better products and consumers win. At this time, IMHO, SRAM has got the group set wars locked down. That’s from hands on experience having ridden many top shelf bikes and group sets since 86. Ride safe and ride often. Always great content Ron. Thank you. Peace.
I'm SRAM Force 22 user for many years, their levers and shifting gears are far better that Shimano. However, I decided to swith to Shimano Dura, simply because I don't like the way SRAM is directing these days and I have enough of messing with front derauilleur adjustment, that is unachievable, no matter what I do, how precise I try to tune it, it always rubbing. Too bad SRAM
@@ronykuba Perhaps. But I'm an old school, at least when it comes to gears and shifting, I preffer mechanical than electronic. For me it's just another unnecessary gadget.
Graphene isn’t toxic, however the oil it’s suspended in likely isn’t something you should be using for salad dressing unless you’re looking for a mean case of the shits.
I remember early last year or a bit before you me getting into some arguments about SRAM. I'm happy to see you come around to Shimano. Obviously I am right about it.
As always interesting to see the lengths you go to find any marginal gain and explore the theory and reality behind it. I’d be interested to learn what’s your take on the new graphine lube vs wax, molten wax, squirt lube or the ceramic speed lube. Thanks for making these Ronnie!
Not sure why you believed that claim that Sram AXS chain is 5w less efficient than Dura Ace 11sp chain. Ceramicspeed’s testing shows the AXS Red chain is 1.5w less efficient than DA 11sp. That drops to only 1w difference with the AXS Force chain.
@@ronykuba 5W seems like a lot, if it is indeed the case, than switching over is totally worth it, you are right 5W is not a marginal gain, that is a big gain. But I am a bit skeptical to the 5W claim, since I've only seen numbers reported of around 5W for the chain friction in total, with differences of about 1 or 2 watts between chains.
I remember you discussed how AXS ratios would be less efficient in the first video you made on it. So I was then surprised you still went all in, not leaving the TT bike alone. I don't think SRAM, or shimano for that matter, really care about drivetrain efficiency. I would like to see what they could do if they dyd.
@@ronykuba SR has an extra gear, for sure is more efficient, it is high end full carbon instead alloy . Expensive is better for your exotic bikes, Di2 is for everyone not for you . As for TT you could use any other brake lever . I apreciate much your evolution, I am fun of you but if you want the perfection you must go to Italy . Everything other is a compromission cost/effectiveness .
@@ronykuba Tell this to Pogacar. Shimano groupset isn't more efficient. DA chain maybe more efficient than Record (max 0,5W) in first 1-200km, but a Campagnolo chain 2 times last longer than a shimano.
Good video but 1.chains are totally and entirely interchangeable between groupsets brands. They have the same width and tooth distance. 2. SRAM doesn't have big chainrings for their new groupsets because they have a 10t cog on the rear. Smaller chainrings means you actually have even more range than before with smaller shifting gaps on the cassette. XD/XDR freehub changed the whole game when it was released and it was rad they gave out the design for free so you can toss it on any wheelset you want. 3. Absolute Black graphene lube is cool but I can't think of a single pro team using them. Real world testing suggests any increased efficiency goes away within half an hour of riding (or one sneeze on the chain). These are really only ridden by non-professional triathletes IMO.
I'm on Campag EPS 11-speed Super Record on one bike and it is flawless. My other 2 bikes are on SRAM eTap AXS 12-speed -- one is Red and the other is Force. First, except aesthetics, there is literally no performance difference between Red and Force, none, so Red is a rip-off. Second, SRAM eTap 12-speed on both Red and Force are annoyingly slooow to engage as you move the chain up into the smaller (harder) gears. Also, i don't like the games SRAM is playing with the chain-ring. The wider gear ratios sound great on paper, but on the road, gimme a 53-39 or 52-36 every day. Will never buy a SRAM eTap drivetrain again. (SRAM Red mechanical is a dream.)
@@ronykuba slow (and by slow I'm referring to a half-second lag in upshift engagement) compared to Campag. Adjustment is not off because it's the same engagement speed on both Red and Force.
I do like innovation but the AB lube cosot is simply absurd. For the money you can almost change chains every 1000km. Just checked for one bottle of AB I can buy 4 chains !!!!! Btw, you need to relube every 600km for efficiency reasons and it needs to be a full flush with spirits otherwise you just start doing the same as with oil after the first prep. Actually beyond 1000km they becoming less efficient anyway. MSW is more efficient and just resets the chain after rewax. So only in case of a race such 5w is worth considering. If you oil your chain all performance gets lost and a much higher rate. The dura ace chain seems to have quite loose tolerances compared to a ultegra chain. And therefor initially shows (irrelevant) better figures. But what about the loss after 500km ? After 1000km ? I believe all this stuff is for 99% irrelevant unless you really compete in a TT setting. In a normal race I don’t even see what it would bring as there many more factors (most important talent) that determine a win
Not really, as there is virtually no wear on the drivetrain. The running costs also need to factor that, not just the price of the lube itself. MSW is still the best option considering price/performance. Yes, I compete in a TT setting, and none of them is 500km long, so it is highly relevant.
In science one study is called one study, not absolute fact. There is a reason why scientific method was created and its because the results of one test are completely useless, there could be any number of hidden issues. You are basing your switch on what one guy says. In other words you based your decision on NOTHING. Your new chain could actually be slower, you literally do not know. In order to know there would need to be a number of independent tests by totally different teams, each peer reviewed by experts. Only then could you say with x confidence that one chain is faster than another. For now though you are chasing ghosts.
Ok smartass, firstly there is a number of independent sources to back it up (MSW, ZFC, Ceramicspeed). Secondly, the result of months of testing from a specialist consulting 8 World Tour teams is not "nothing". Also, there is a clear historical pattern in Sram chain efficiency - Red22, XX1, Eagle chains were all less efficient than their peers
"I known from long that sram made durable chains" you more seem to adjust your everyweek 5k$ buying to the marginal watt saving you read on bicyclerollingresistance or aerocoach/friction facts rapports. I think beeing on the ultra consumerist side of riding affect a bit your legitimity as a cyclist... your building your ego on leaving poorer than you dreaming of tech they cant afford !
I don't really have a reason to doubt information from someone consulting 8 WT teams, including the recent TdF winner and runner up. 5W is not a marginal gain, and I had TT nationals to do. I run a bike business. The more products I try, the more experience I have so I can give better advice to my customers. If you think that's undermining my credibility you have it a little bit backwards. And that last sentence... wtf...
@@ronykuba 5:52 And that trek ♥️ I bought 3 months ago sl6 pro disc 2021 with ultegra. New 60mm and 88mm wheels ffwd are coming for next season also 😉 take care ✌🏻
The theoretical watt difference between the two sets is hard to realized when the greatest variable, the human, comes into play. The human must be at 100% on every use to realize the difference. BTW, those carbon cages have broken on me 3 times. I've given up on them. They always crack at the screw point.
Wrong. If something is more efficient, it's more efficient, doesn't matter if you're doing 150 or 350W. As for the cages, that's why torque wrenches exist.
Experience in material, production technology and the return of field experience can make the difference for sure. Geometry and construction can be copied quickly.
Its hard to argue against Di2, I have used it for years. Perfect shifting every time . A joy to use.
True
Not really,
Ive used etap for 3 years and its worked flawlessly, never dropped a chain even on a 1x with a standard clutchless rear derailleur, but what really sells it to me compared to Shimano is that you don't have to run a wire through the frame.

@@s.nherat1772 Sram Red AXS is the top end road groupset if that's what you are asking. Shimano is more efficient as per the things said in the video
@@ronykuba Many thanks Ronald.
Ignoring everything else would the most efficient drive have a 17t as the smallest cog?
Possible yes, but there are other factors to consider
Hi. Thanks for your videos. I see in your other video you have xx1 AXS on your MTB.
My question is, do you think xtr di2 is better than xx1 AXS for MTB? Also I came across an article suggesting xx1 AXS + xtr cogs and chain would be "mismatch made in heaven".
Would like to know your thoughts on this. Cheers.
XTR di2 is hopelessly outdated, although it uses the same chain as Dura Ace. For XX1 there are efficient chain options, I don't think mismatching stuff would make much sense.
What's the big pulley on the rear mech?
Ceramicspeed OSPW
I agree axs flattop chains are very limiting. One idea I am considering is to changebto regular 11 speed chain, change the cassette and chain ring to suit..... And reprogram the axs groupset to work to 11 speed. Mind you the derailleur pullrys may need to be changes too.... As spacing of axs chain Rollers are different. Just a thought.... Haven't tried that yet but I believe that would be a hack without having to change over entire group set.
I don´t think reprogramming would be financially reasonable
Thank you for sharing the difference in efficiency between SRAM and Shimano’s.
Do you know of any published findings to support the claim?
I am unable to find anything to support the claim on the internet.
5 Watts is a big difference indeed.
AbsoluteBlack doesn't share it's test data I'm afraid

Only the Venge and Shiv are mine
Rony, I did the same thing. I've been a loyal eTap user for 2+ years. It is just so simple to install and the brake bleeding for the HRD version is better in my opinion. I think wireless is great and being able to take out the batteries easily is great for those of us who travel with bikes. I got a new bike with Shimano Di2 and within one ride, I was smitten. The shifting is better and 1000 miles later- no chain drops. The shifting works fantastic- even with low rpm. I use a 53/36 and 11-30 and this works great for me in the SF Bay Area. The drawbacks for Shimano for me are the inconsistencies in the power meter readings from the r9100 (GPLama has a great bit on this) and the connection dropouts with the bluetooth unit.
Yes it's better to stay with Quarq for power
The shimano powermeter is shite. Buy Quarq or put some Assiomas on it to get the best out of your training.
Hi Ranold,
I'm using sram red axs 1X 50T, 10-33T and I just bought 60T front chainring. Do you know sram red flattop chain long enough for this 60T chainring?
Probably not

This years tour, a majority of the teams now on Shimano. Sponsorship or Choice?
the123roman Shiamno has been the main sponsor of world tour teams for ages now!
Sponsorship
But there are a few world tour teams that are not sponsored by Shimano like Astana or Israel start up nation and no team without a groupset sponsor uses SRAM or Campagno.
The teams that don't have a groupset sponsor, are all on shimano.
Very simple. Shimano does everything better and is lighter. I hate my Force AXS
AndreasHappyfarm you sound like the typical guy to claim to have SRAM AXS, but doesn’t.
@@LarsRR Cool. One XX1 AXS Santa Cruz Blur. One Cervelo Aspero 2x Force AXS. One Argon18 Nitrogen Pro Ultegra Di2 R8070. What du you own?
Well, not everything. There's no perfect groupset unfortunately.

All of the work perfectly.
@@LarsRR Yes it works fine, but not with the speed of Shimano. I really like my XX1 AXS stuff. But riding Force back to back with Di2 makes the deficiency pretty obvious. Everyone I know that rides both feels the same way. Shimano brakes better, shifts faster, weighs less, makes less noise and is better made.
Ronald, I really appreciate your neutrality and keeping an open mind to experiment. Agree on the "fanboyism" - it's just pros/cons that are highly subjective to a rider's use-case. BTW - Quick question: Any thoughts on the Kogel OSPW? They claim to have a stiffer cage than Cermaicspeed to improve shift performance.
It seems to be stiffer, but I can't really tell a difference in shift performance.
@@ronykuba Thanks, that's all that matters.
Did you just put a 1x chainring on your di2 and it worked straight away?
Actually, the ring was already there. It was the groupset that has been changed.
just push the button on the junction box to turn off the fd for 1x
@@ronykuba So why are people saying Sram is way better for 1x?
@@graphics_dev5918that only switches between the shift modes. You can't just go ahead and turn off the FD when installed.
@@hazzyboy3456 the new AXS RD has a clutch in it, but it's not really required with a 58t narrow wide ring.
I prefer Di2 over Etap even though Di2 is a puzzle to install and it doesn't have a 12 speed cassette with a 10t cog... I guess I'm weird?
I don't think so
Anthony HT I prefer Di2 and ride a 14-28 cassette. Never need smaller cogs. Am I weird?
I thought KMC SL would be better than the shimano one, isn’t this the case?
It's not
Ronald Kuba why not use 11 speed etap with shimano chain? This seems to be the best option now given how simple the setup is for SRAM.
@@govody there's no place to put the Blip Box, the front shifting is not great, and the old monoblock calipers are problematic.
Ronald Kuba can’t argue with all these points!
What Di2 shift mode do you use?
Manual
Why not syncro shift?
@@benbisson9608 i myself didnt like syncroshift because i like to be in the 53 chainring as long as possible during races. found it frustrating during training, and went manual. Power transfer feels better on the big ring and changing from small to big ring on top of the climb just takes an extra second or two.
@@benbisson9608 you can't use that for racing
@@benbisson9608 I used semi synchro for a bit.
And then I just go back to manual. Even compensation rear shift when I shift the front is not always required. So I'd rather have full manual control.
nice one, thanks , I did not know about the gap on chain efficiency! was it a mother or gf at the end saying ' no w koncu!' :)
Glad it was helpful! Yes it was Malena
Respectfully. Summer of 2019 after receiving my near first issue Red AXS and soon after completed the California Death Ride 120 miles 15k climbing all in the altitude of the Sierras in 6.5 hrs and then this year road the route of Colorado’s Triple By-Pass 120 miles and 10k of climbing all in the altitude with a couple of friends all with zero issues. All aboard my Moots Routt RSL. This group is sublime. Easy to use and bullet truly proof. SRAM has truly set the bar IMHO and continues to evolve. Batteries clicked out of their cradles and charged versus moving your entire bike over to attach a charging cable to an outlet. On road change of batteries is so easy, front to rear, rear to front, no problem. All charging diagnostics read from your phone, easy. Shimano, always a juggernaut seems to be in a holding pattern at the moment. No substantial enhancements or streamlining. Not sure why but I’m sure there’s something on the horizon in that camp. You can count on it. Competition makes for the better products and consumers win. At this time, IMHO, SRAM has got the group set wars locked down. That’s from hands on experience having ridden many top shelf bikes and group sets since 86. Ride safe and ride often. Always great content Ron. Thank you. Peace.
True, thanks for the support!
This is very informative. Thanks for sharing
Glad it was helpful!
I'm SRAM Force 22 user for many years, their levers and shifting gears are far better that Shimano. However, I decided to swith to Shimano Dura, simply because I don't like the way SRAM is directing these days and I have enough of messing with front derauilleur adjustment, that is unachievable, no matter what I do, how precise I try to tune it, it always rubbing. Too bad SRAM
Well, the AXS front shifting is actually pretty damn good
@@ronykuba Perhaps. But I'm an old school, at least when it comes to gears and shifting, I preffer mechanical than electronic. For me it's just another unnecessary gadget.
How toxic is that graphine lube stuff? Any idea?
I don't know that
Graphene isn’t toxic, however the oil it’s suspended in likely isn’t something you should be using for salad dressing unless you’re looking for a mean case of the shits.
I remember early last year or a bit before you me getting into some arguments about SRAM. I'm happy to see you come around to Shimano. Obviously I am right about it.
I didn't switch because of the mineral oil, did I?
Can you feel in difference in chain efficiency while on the road?
These are not things you can feel
As always interesting to see the lengths you go to find any marginal gain and explore the theory and reality behind it. I’d be interested to learn what’s your take on the new graphine lube vs wax, molten wax, squirt lube or the ceramic speed lube. Thanks for making these Ronnie!
Cheers! We will see about the Graphene lube after more testing
Not sure why you believed that claim that Sram AXS chain is 5w less efficient than Dura Ace 11sp chain. Ceramicspeed’s testing shows the AXS Red chain is 1.5w less efficient than DA 11sp. That drops to only 1w difference with the AXS Force chain.
At which output?
@@ronykuba 5W seems like a lot, if it is indeed the case, than switching over is totally worth it, you are right 5W is not a marginal gain, that is a big gain. But I am a bit skeptical to the 5W claim, since I've only seen numbers reported of around 5W for the chain friction in total, with differences of about 1 or 2 watts between chains.
@@ronykuba I believe CS test at 250w
why is this 5w difference between chains ?
Design, construction
so its fundemental.
What bottle cages are those?? Thanks!

I remember you discussed how AXS ratios would be less efficient in the first video you made on it. So I was then surprised you still went all in, not leaving the TT bike alone. I don't think SRAM, or shimano for that matter, really care about drivetrain efficiency. I would like to see what they could do if they dyd.
True, maybe for the next generations they'll start to implement some changes.
the dura ace cassettes are so loud in the 4 smallest cogs. thats what makes dura ace really shit although i like shimano
They're not my favourite either
Why not Super Record EPS?
Shimano is more efficient. Also a lot cheaper, plus Campagnolo don't even have disc brake TT brakes
@@ronykuba SR has an extra gear, for sure is more efficient, it is high end full carbon instead alloy . Expensive is better for your exotic bikes, Di2 is for everyone not for you . As for TT you could use any other brake lever .
I apreciate much your evolution, I am fun of you but if you want the perfection you must go to Italy . Everything other is a compromission cost/effectiveness .
@@gpanoutsak I'm talking about drive train efficiency. Carbon construction will not do much in that regard.
@@ronykuba Are You kidding us? TT bike with disc brake? Craziest thing in cycling.
@@ronykuba Tell this to Pogacar. Shimano groupset isn't more efficient. DA chain maybe more efficient than Record (max 0,5W) in first 1-200km, but a Campagnolo chain 2 times last longer than a shimano.
Wise choice.. shimano is way better, plus those secret buttons to control Garmin is exclusive to Shimano!
...which I was never going to use even if I had a Garmin
Ronald Kuba you can programme for them gear shifting instead..I just think it’s one hell of a bonus feature as I use them a lot.
Good video but
1.chains are totally and entirely interchangeable between groupsets brands. They have the same width and tooth distance.
2. SRAM doesn't have big chainrings for their new groupsets because they have a 10t cog on the rear. Smaller chainrings means you actually have even more range than before with smaller shifting gaps on the cassette. XD/XDR freehub changed the whole game when it was released and it was rad they gave out the design for free so you can toss it on any wheelset you want.
3. Absolute Black graphene lube is cool but I can't think of a single pro team using them. Real world testing suggests any increased efficiency goes away within half an hour of riding (or one sneeze on the chain). These are really only ridden by non-professional triathletes IMO.
1.) except AXS with the large diameter rollers
2.) Smaller cogs and rings = significant increase in friction
3.) UAE Emirates
shimano great for races, sram all rounder, both superior product
true!
I'm on Campag EPS 11-speed Super Record on one bike and it is flawless. My other 2 bikes are on SRAM eTap AXS 12-speed -- one is Red and the other is Force. First, except aesthetics, there is literally no performance difference between Red and Force, none, so Red is a rip-off. Second, SRAM eTap 12-speed on both Red and Force are annoyingly slooow to engage as you move the chain up into the smaller (harder) gears. Also, i don't like the games SRAM is playing with the chain-ring. The wider gear ratios sound great on paper, but on the road, gimme a 53-39 or 52-36 every day. Will never buy a SRAM eTap drivetrain again. (SRAM Red mechanical is a dream.)
The whole point of a lower tier groupset is the same functionality, with more weight and thus cost saved. If they are slow, the adjustment is off.
@@ronykuba slow (and by slow I'm referring to a half-second lag in upshift engagement) compared to Campag. Adjustment is not off because it's the same engagement speed on both Red and Force.
Lol I’m not a fan is only possible if you don’t Pick any groupset.
why would that be?
Because you have money... that's why you switched... God dam bro..
I do like innovation but the AB lube cosot is simply absurd. For the money you can almost change chains every 1000km. Just checked for one bottle of AB I can buy 4 chains !!!!! Btw, you need to relube every 600km for efficiency reasons and it needs to be a full flush with spirits otherwise you just start doing the same as with oil after the first prep. Actually beyond 1000km they becoming less efficient anyway. MSW is more efficient and just resets the chain after rewax. So only in case of a race such 5w is worth considering. If you oil your chain all performance gets lost and a much higher rate. The dura ace chain seems to have quite loose tolerances compared to a ultegra chain. And therefor initially shows (irrelevant) better figures. But what about the loss after 500km ? After 1000km ? I believe all this stuff is for 99% irrelevant unless you really compete in a TT setting. In a normal race I don’t even see what it would bring as there many more factors (most important talent) that determine a win
Not really, as there is virtually no wear on the drivetrain. The running costs also need to factor that, not just the price of the lube itself. MSW is still the best option considering price/performance. Yes, I compete in a TT setting, and none of them is 500km long, so it is highly relevant.
In science one study is called one study, not absolute fact. There is a reason why scientific method was created and its because the results of one test are completely useless, there could be any number of hidden issues. You are basing your switch on what one guy says. In other words you based your decision on NOTHING. Your new chain could actually be slower, you literally do not know. In order to know there would need to be a number of independent tests by totally different teams, each peer reviewed by experts. Only then could you say with x confidence that one chain is faster than another. For now though you are chasing ghosts.
Ok smartass, firstly there is a number of independent sources to back it up (MSW, ZFC, Ceramicspeed). Secondly, the result of months of testing from a specialist consulting 8 World Tour teams is not "nothing". Also, there is a clear historical pattern in Sram chain efficiency - Red22, XX1, Eagle chains were all less efficient than their peers
Shimano is just better imo! The pro peloton tells the story!
well, that is not always the best indicator for the normal consumer
"I known from long that sram made durable chains" you more seem to adjust your everyweek 5k$ buying to the marginal watt saving you read on bicyclerollingresistance or aerocoach/friction facts rapports. I think beeing on the ultra consumerist side of riding affect a bit your legitimity as a cyclist... your building your ego on leaving poorer than you dreaming of tech they cant afford !
I don't really have a reason to doubt information from someone consulting 8 WT teams, including the recent TdF winner and runner up. 5W is not a marginal gain, and I had TT nationals to do. I run a bike business. The more products I try, the more experience I have so I can give better advice to my customers. If you think that's undermining my credibility you have it a little bit backwards. And that last sentence... wtf...
Come on... how could you judge the durability of a chain, you change your bike every 3 mounths 🤣
Yeah, literally everything about shimano is better. Until shimano goes wireless, I couldn't care less about it.
Not everything for sure

Shimano chain vorks with Sram drivetrain vice versa
not 11spd Shimano with Sram AXS
The theoretical watt difference between the two sets is hard to realized when the greatest variable, the human, comes into play. The human must be at 100% on every use to realize the difference. BTW, those carbon cages have broken on me 3 times. I've given up on them. They always crack at the screw point.
Wrong. If something is more efficient, it's more efficient, doesn't matter if you're doing 150 or 350W.
As for the cages, that's why torque wrenches exist.
Obviously not a fan of saving money either by using a useless ceramic speed OSWP….
What if I told you that I have enough money to not worry about saving on bike parts?

That's relative
SRAM founded 1987; Shimano 1921. It’s just simple as that.
Tolga 71 that’s one stupid point. Campagnolo invented the sifting groupset. So they should be the best still, simple as that!
That's not a very good point
Experience in material, production technology and the return of field experience can make the difference for sure. Geometry and construction can be copied quickly.
