How about a Di2 app where you input your preferred cadence range and it senses your powermeter/heartrate and shifts to the most optimal gear. A beep would warn you of impending shifts so you're not surprised. The system could also sense sudden power surges and accommodate. Kinda like an automatic transmission. Buggy at first, but it would "learn" your preferences.
Poor Alex turned red like a tomato when he recalled crying after his awful bonk in Mallorca. Nothing to be embarrassed about, mate. You had a terrible day, you did your best and we are proud of you.
Watching Simon on the Tech Show doing the Bike Vault segment caused me to reminisce back to the days when he and Dan rated the bikes as either, "Fine" or "Splendid." "Fine" or "Splendid"--so British! Enjoyed the show as always. Keep up the great work!
Archer's system can do exactly what Alex suggested. Select the number of gears and then just adjust the spacing. I have this on my fatbike, works great
related- I have a Di2 Alfine 11 sp internal hub, and a wheel with an 11 speed cassette and a Deore XT 11 speed deraileur. I swap those two setups, and the Di2 identifies them.
Maybe ‘Dr O’ (Bond villain?), thought carrying even one spare inner tube would be too detrimental to his ‘aero enslavement’? Or not. Great video and shows how fit Dr O is and how genuine a bloke Alex is. Chapeau to them both.
Hi Alex Bad Boy Supreme, There are heated gloves and some are quite thin and offer good dexterity. They run on a small battery and keep your hands toasty warm. That would seem to be a better and more energy efficient solution to your cold hands problem than heating the entire handlebar.
Frequently I am a bit lukewarm on the Tech show but the chemistry this episode was on point. Great banter and fun topics. I have to give this one a “SuperNice” for sure!
The reason you can't reprogram an electronic groupset is money. They want you to buy the new part. Plus, it's cheaper to develop a device that doesn't have to be reprogrammed.
RE: Waterproofing your feet. I'm a whitewater kayaker, and we paddle a lot in the cold temperatures. We use Dry-suits, which have latex gaskets at the neck, and wrists, along with a waterproof zipper for entry, and another for relieving yourself without having to take the whole thing off. Quality ones are made of Gore-Tex materials(see Kokatat GMER), and have integrated booties, which you put your river/water shoe of choice over. So on really cold days, a couple of pairs of wool socks under the dry-suit booties, then a water shoe, and your warm, toasty and dry all day, even if you take a swim, or have to do any wading around. Gore-Tex has the tech and knowhow to be able to do the same thing on a pair of bib-tights. Why haven't they? Also, Sealskinz make an excellent waterproof sock. One thing you DO NOT want to do is to put a latex gasket at your ankles, as even a small amount of pressure there can slow the blood flow to your feet making them way colder. Great show as always!
The tech you wish for programming the derailleur to how many gears you have exists with chinas L-Twoo So the technology exists but Shimano and sram probably want you to just buy new replacements.
I believe one of the Chinese groupset brands does exactly what Alex has described. I can imagine the reason is ££££. It means you have to buy a whole new groupset.
Replying to get this comment up. I've seen those L-Twoo groupsets that I've heard can be programmed to 10,11 and 12 speeds thru an app, for the same weight as 105 Di2. In my region (Australia), its even almost half the price of 105 Di2.
Heated grips are great on a motorbike, but if your hands are cold on your bicycle, you need to think about your clothing. Cold hands aren't really caused by your hands being out in the wind, it's largely down to peripheral heat loss. Once you have a half decent pair of gloves on, if your hands are still cold you need to warm your body core rather than adding heat to your fingers.
Si, did you not mention that you were out with your mates recently and had to "borrow" some inner tubes ... pot calling the kettle black. Ollie deserves the ribbing as GCN Tech Groupen Furer (sorry, umlaut missing)
Alex saying "12 speed for the price of a chain and cassette" at 6:50 or so and wondering why it doesnt exist... Well that is precisely why. Selling new groupsets
In my experience, Muc-off sealant never dries out. It's still liquid a year after being put in the tires. Unfortunately that also means that it never really seals a puncture (unless adding glitter or something to it).
The reason for the Di2 gearing is money. It would purely be a software things. LTWoo have the ability to ride 11 or 12sp gearing at the back through the app.
At least a couple are already available. Shimano Di2 hydraulic shifters could be made with 'flat - ish' tops as the piston and cylinder assembly are running parallel to the floor. You can select speeds in L-Twoo electronic groupset
Heated grips are rubbish, they cook your palms like a barbecue, but the rest of your hand's still frozen. Heated gloves - which already exist - are the way to go! That's how i've found them to be, a motorbike in winter.
There are so hair raising assumptions about the principle of smart trainers and electricity in general. 😄 First of all the power consumption. Turbo trainers only require something in the region of 2 Watts. They just need to run their tiny “computer” to send and receive data. So Alex you can hammer your sessions because all the energy you put into the pedals is simply converted into heat. Adding to that the 300 Watts you mentioned is actually quite some power. Here are some examples: Charging your phone 10W, charging your tablet 40W, a TV or notebook 60W, a very big dehumidifier to protect Ollie’s bike 200W. Even a solar panel has a peak power of only 400W. Actually we are quite powerful. Change currency and 300W are half a horsepower. Half a horse doesn’t sound weak at all 😉
Ltwoo electronic groupset can be set to 10, 11, or 12 speed. It's great because someone can buy it and worry about changing cranks, cassette, and possibly hub driver later.
I'm with Alex on the electronic options for gearing. I have that on my Stages SB20 smart bike, and it is bloody brilliant. If I plan to ride a route with heavy intense mountains, I can pick the gearing I need to do that with. 2x, 1x, SRAM, Campy, Shimano, flat routes, put a 55 tooth up front and hammer speed, rolling hills, no problem, 10-33 or 11-30... it is fantastic.
I would suggest making jingles out of Si's blowing nose noises and putting that under the show's different chapters, Hot & Spicy Tech, Comment of the Week, Bike Vault, etc... It would make the whole "more aero, more lightweight, more Di2, more carbon, oh the wheels are not aligned" snobism a little bit humane. Thank you :) And now on a more serious side, I really like your shows and the chemistry between you guys so... ride on
Si mixed up two (equally good) different Simpson's episodes. The car Homer designed was called the "Homer" and was in the episode where Homer's long lost brother, Herb, comes back into his life (played by Danny Devito). The episode with the car, called the Canyonero, was in the episode where Marge gets a SUV and it causes her to drive aggressively. Still happy to see classic Simpson's referenced, despite the mistake.
Alex talking about electronic groupsets that can be programmed for different speeds, It has been done. L-Twoo ERX groupsets can be set to 10, 11 or 12 speed through its firmware app, but the groupset is hydraulic disc only. The biggest issue with reverse engineering it for fewer gears is that most of the older groupsets are cable (rim or disc) brake only.
Re the water dripping into your overshoes thing. Unless it's really baltic, I ride with 3/4s in the winter. So, I don't even get the benefit of the bottom bit of the tights leg delaying the inevitable. For many years now, the cuffs from a pair of rubber gloves (Marigolds or any kitchen type washing up gloves) have done the trick for me. Water runs down the shins /calf over the cuff and onto the overshoe. Works a treat and takes (on average) 3 1/2 to 4 hrs riding in really bad weather for the socks to begin to dampen. Mind you, Zwift means that I ride indoors if the weather will be bad all day.
I use Sporthill XCski pants over winter cycling shoes. All the water runs on the outside of shoe & not quite lycra tights, but flexible & comfortable in a large range of temps.
Heated handlebars and hoods 🤤. Also, Tukas EV reminded me of Tuchas EV. 🤔 Also, re: calling Chloe crying, it's understandable. I'm still blown away you finished the ride and relieved you're alright. Monumental effort.
A regular indoor trainer certainly does not consume 300 watts of electricity if you’re riding at 300 watts. The power you produce is converted to heat, which is why the ”drum” on the trainer is hot after a ride. In the winter you presumably have to heat your house, in which case all the energy you produced goes into good use, even if it’s not used for charging batteries of powering TVs.
I agree with Si that I'd like a little more travel with my road disk brake calipers so the pads retract more and never touch the rotor when not being compressed.
Si, Finish line sealant doesn't dry out because it's not water or latex based. Tax Neo 2T trainer can be used without mains power, you provide the power.
5:30 people forget how much that light rimbrake bikes/frames were braking. I think it’s better (especially at aero bikes) to have that few grams more material.
Sorry Si, your Simpsons knowledge is slightly lacking - while the Canyonero did feature in the Simpsons episode "The Last Temptation of Krust" with a memorable Krusty endorsed commercian (Canyon-errrooo....hyah!), the vehicle that homer designed was called..."The Homer". In fairness I had to look most of that up but I did know the Canyonero wasn't the vehicle homer designed ;) Agreed though that Yamaha thing is uuuugly.
Can someone please explain why it's so funny that Ollie's bike was upside down when fixing the flat tire? The worst that could happen on a very wet/muddy would be that you get a little water and grit in the contacts of any internal routing. Secondary would be, oh no , your saddle and hoods would get a little scuffed. Compared to what? Front wheel out, you're grinding the fork ends on the ground chipping away the protective paint. Rear wheel out you have your chainring/rear derailleur/rear stay grinding against the ground. I've seen this said several times on GCN without a proper explanation. What are the alternatives? Lay the bike on its side on the road and scrape the frame? Please tell me what I'm doing wrong by setting my bike upside down for a roadside flat fix.
Yes. But not everyone wants a cheap chinese groupset that isn’t quite up to middle-tier spec in regard to workmanship, design, bearing quality, performance, or weight. There is a lot more to high performance than the number of cogs in the cassette.
Don't forget the extra weight of spokes in the front wheel with disc brakes - they can't be radially spoked or laced 2-cross; under braking the wheel might experience more tangential force than the rear wheel under acceleration.
2-cross is OK with discs, isn’t it? Maybe not quite as robust as 3x, but I’ve been running 24 spoke 2x on my CX bike for a while and it hasn’t killed me yet.
@@Steve.M 2 cross probably okay then, but the braking forces aren't as high in cx as on warm tarmac. If it's okay in a rear wheel it'll probably be okay on the front..? 🤷♂️ I don't know if there have been any studies on this
One can actually power a lot of useful things of a power an average rider can output for a long ride. For example - a laptop, a TV and the bike trainer itself indefinitely. And a trainer never draws even close to your watts. It's just adjusting the position of magnets and consumes around 14 watts or less then no matter what you do. Rest of your power in dissipated as heat
Exceptional fun show Alex and Si! Bike manufacturers sometimes do go too far and Si's expression "You've taken everything that's good about bikes and ruined it!" is right on and very funny. On the subject of pedaling to generate electricity, it's been done. Years ago I read of an engineer (with a bit of a mean streak I guess), who made electric generators that his kids had to pedal to generate power if they wanted to watch TV, and this was in the last century before digital electronic devices with a lighter power draw were common. I'm imagining a scene where an adventure story ends in a unscheduled 'cliffhanger' because the TV started to fade and the kids couldn't pedal fast enough to see the ending.
Cableless/Hoseless brakes! It's gotta be top of the list guys! No more faffing around with internal or external routing! Automated bike fit! You get on the bike and everything moves to optimally fit you! A bit like expensive cars when they have like 6 different programmable seat positions so there's no arguments getting back in the car after the wife has been driving! The other benefit would be , several people could use the same bike!
Chinese groupset brand LTwoo allows you to choose 10, 11, or 12s with the same group. A cheap upgrade path so you can move to electronic shifting in 1 step, then later move to 12s
Have you never heard of heated gloves or over trousers? They have been around for a while now. On a video production point: please reposition a reflective surface that is on your shelf off screen, Manon's photo in the background looks like she has something coming out of her nose.
Not sure about inner tubes, but a well-timed poo break can get you a word champion title, think Mathieu van der Poel. Olie needs to learn how to time those if he wants to up his performance game!
I guess the answer to why there's no Di2 app to change from 10 to 12-speeed for example is just the fact that if you wanted to upgrade to a 12-speed, you'd have to go ahead and buy a full 12-speed Di2 groupset, which would give the manufacturer a bigger revenue than only selling a 12-speed chainring which you can mount on your Di2 system. You know what they say: Money makes the world go round....
And there is a technical part to it too. When a manufacturer makes 9 speed compatible derailleur, its tolerances are insufficient for 12 speed spacings. Unless the 9 speed part is done to higher tolerancesfrom the start, just like current cross-compatible CUES
million % agree on being able to tell electronic shifters how many shifts it should do, it would open so many doors and chances to mix and match different gear, and so many paths to upgrade your system.
If you could program your groupset to now use 12 speed with a new cassette and chain, then there wouldn’t be any reason to buy a new 12 speed derailer… so the legit reason why this doesn’t exist is because the groupset makers would lose a lot of $$…
I've always wondered why my turbo trainer isn't powering a remote fan that is linked to the speed I'm riding. More effort more wind. Can't be that hard?
🤣🤣🤣🤣🤣 You are a genius... The heated handlebar it is! Wonder why I didn't thought of that... IF that's not a possibility, heated gloves then, it works too!
I wish gearboxes were not as heavy as they are today. Not because of speed, but because heavy gearboxes make bikes awkward to carry (e.g. upstairs). Also, brifters for gearboxes are rare (sometimes nonexistent).
Don't know if someone already recommended using latex sealant on a tubular tire. I still ride tubulars due to the great ride feel/performance and carry a 2 oz. bottle of sealant on all my long rides (100 to 160+ km rides). Have found that tubs hold sealant better than clincher tubes which still work as well to effectively seal most punctures (90+%). My tubulars have lasted 2-2.5 years (100's of rides) using latex sealant. Cheers!
To Si's point - A poop can have significant weight. I've weighed myself before/after, and I've seen up to 4 pounds for a large one. Get rid of that excess weight!
What bike tech do you wish existed? 🚲👇
One with external cables, threaded bottom bracket,. non specific brand stem / handlebars and round seatpost.
How about men's cycling shorts with a fly to make bathroom breaks easier.
Fully wireless Di2, similar to SRAM. Dura Ace cassettes with a wider range of gears, like an 11-34
A titanium cranium! So I can feel light-headed all the time 😁
How about a Di2 app where you input your preferred cadence range and it senses your powermeter/heartrate and shifts to the most optimal gear. A beep would warn you of impending shifts so you're not surprised. The system could also sense sudden power surges and accommodate. Kinda like an automatic transmission. Buggy at first, but it would "learn" your preferences.
Not Tech, but I'm nominating Alex for the 'Best Bonk Of 2023' for his lap of Mallorca. We need a 'Bonk Vault'. Super Nice Alex!!

You can choose how many gears you want in L-twoo electronic, between 10-12
Mind Blowing Tech 🤯
Fair play to Alex for sharing his despair call with Chloe it’s great genuine content love it 😊
Archer's system can do exactly what Alex suggested. Select the number of gears and then just adjust the spacing. I have this on my fatbike, works great
We might have to take a look into that 🔍
Beat me to it
I'm making a list of the hundred or so mistakes and omissions in this episode, Archer and Ltwoo definitely make the list !
related- I have a Di2 Alfine 11 sp internal hub, and a wheel with an 11 speed cassette and a Deore XT 11 speed deraileur. I swap those two setups, and the Di2 identifies them.
L-TWOO has this option aswell, its only the big brands that dont offer this feature
Maybe ‘Dr O’ (Bond villain?), thought carrying even one spare inner tube would be too detrimental to his ‘aero enslavement’? Or not. Great video and shows how fit Dr O is and how genuine a bloke Alex is. Chapeau to them both.

Carbon spokes mostly take care of this
One can actually power a lot of useful things of a power an average rider can output for a long ride. For example - a laptop, a TV and the bike trainer itself indefinitely. And a trainer never draws even close to your watts. It's just adjusting the position of magnets and consumes around 14 watts or less then no matter what you do. Rest of your power in dissipated as heat
Ooof….Ollie will be fuming at Si for awarding that jaunty angled Ribble a “Super Nice”
Self charging elektronic groupset. Its pretty easy to design. It is an impertinence that they hide this invention in their drawers
Exceptional fun show Alex and Si! Bike manufacturers sometimes do go too far and Si's expression "You've taken everything that's good about bikes and ruined it!" is right on and very funny. On the subject of pedaling to generate electricity, it's been done. Years ago I read of an engineer (with a bit of a mean streak I guess), who made electric generators that his kids had to pedal to generate power if they wanted to watch TV, and this was in the last century before digital electronic devices with a lighter power draw were common.
I'm imagining a scene where an adventure story ends in a unscheduled 'cliffhanger' because the TV started to fade and the kids couldn't pedal fast enough to see the ending.
Alex’s idea for a 9/10/11 variable speed electronic groupo already exists- just need to hop on the LTwoo train! China’s one step ahead
Lots of people pointing this out... think it's time Alex gets his hold on some 👀
🙌 collab between Alex and Trace Velo pretty please

Cableless/Hoseless brakes! It's gotta be top of the list guys! No more faffing around with internal or external routing! Automated bike fit! You get on the bike and everything moves to optimally fit you! A bit like expensive cars when they have like 6 different programmable seat positions so there's no arguments getting back in the car after the wife has been driving! The other benefit would be , several people could use the same bike!
Chinese groupset brand LTwoo allows you to choose 10, 11, or 12s with the same group. A cheap upgrade path so you can move to electronic shifting in 1 step, then later move to 12s
Have you never heard of heated gloves or over trousers? They have been around for a while now. On a video production point: please reposition a reflective surface that is on your shelf off screen, Manon's photo in the background looks like she has something coming out of her nose.

LTWOO ERX electronic groupset can be set to 10,11 and 12 speed via their app
Si needs to get some Spatz, warm and dry feet all winter!
Great fun to se the A Team in action
There’s a wind tunnel test to be had there. Pr Ollie pre poo and post poo, with pre and post weigh in
Thanks for featuring my #bikevault submission 😃
Chinese electronic l-two can switch between 11 and 12 speed for rear derailleur.
Not sure about inner tubes, but a well-timed poo break can get you a word champion title, think Mathieu van der Poel. Olie needs to learn how to time those if he wants to up his performance game!
Archer Components make an electronic shifting system that works with any rear mech which can be programmed to shift anywhere from 2 to 20 gears.

I guess the answer to why there's no Di2 app to change from 10 to 12-speeed for example is just the fact that if you wanted to upgrade to a 12-speed, you'd have to go ahead and buy a full 12-speed Di2 groupset, which would give the manufacturer a bigger revenue than only selling a 12-speed chainring which you can mount on your Di2 system. You know what they say: Money makes the world go round....
And there is a technical part to it too. When a manufacturer makes 9 speed compatible derailleur, its tolerances are insufficient for 12 speed spacings. Unless the 9 speed part is done to higher tolerancesfrom the start, just like current cross-compatible CUES
@@feedbackzaloop I did not know that! Cheers for sharing!
million % agree on being able to tell electronic shifters how many shifts it should do, it would open so many doors and chances to mix and match different gear, and so many paths to upgrade your system.
Maybe it's on it's way 👀 Watch this space!
If you could program your groupset to now use 12 speed with a new cassette and chain, then there wouldn’t be any reason to buy a new 12 speed derailer… so the legit reason why this doesn’t exist is because the groupset makers would lose a lot of $$…
I've always wondered why my turbo trainer isn't powering a remote fan that is linked to the speed I'm riding. More effort more wind. Can't be that hard?
Use the bike tire or cranks to charge the di2. I don’t think it will slow the bike at all and you will never have to charge your group set.
🤣🤣🤣🤣🤣 You are a genius... The heated handlebar it is! Wonder why I didn't thought of that... IF that's not a possibility, heated gloves then, it works too!

I wish gearboxes were not as heavy as they are today. Not because of speed, but because heavy gearboxes make bikes awkward to carry (e.g. upstairs). Also, brifters for gearboxes are rare (sometimes nonexistent).
Don't know if someone already recommended using latex sealant on a tubular tire. I still ride tubulars due to the great ride feel/performance and carry a 2 oz. bottle of sealant on all my long rides (100 to 160+ km rides). Have found that tubs hold sealant better than clincher tubes which still work as well to effectively seal most punctures (90+%). My tubulars have lasted 2-2.5 years (100's of rides) using latex sealant. Cheers!
To Si's point - A poop can have significant weight. I've weighed myself before/after, and I've seen up to 4 pounds for a large one. Get rid of that excess weight!
We need a GCN Tech show with Dan Lloyd
Dan doesn't ride bikes anymore ... just watches racing 🚴
The l-too erx groupset is compatible with 10 11 12s cassettes , iv also put abit of tubless fuild in my tubs never have a puncher 👌
Heated grips on my BMW are awesome.
#does have it’s own 1200cc in built generator!
Come on, Si.. The Canyonero was the SUV that Marge bought. The car that Hover designed was called "The Homer."
Chinese company Ltwoo offers an electronic group-set (ERX)where via the app, you can set it to work as 11 speed or 12 speed
L-Twoo's (Chinese manufacturer) electronic groupset does give you the option of setting the group as either 10, 11 or 12 speed from their app.
Tech I wish existed: cheap and reliable dynamo and lights setup
You can buy heated motorbike gloves
Wow, Si not sure you are the right one to mention a lack of tubes/spares.
