Looking for that first tri bike? These are the best beginner triathlon bikes for 2020 ruclips.net/video/rScVpWcwWlo/видео.html
I can't believe no one has done a clip-on aero bars vs. tri bike comparison yet. That's probably the comparison that impacts beginner triathletes the most.
Would love to see a comparison with the drops being used on the road bike.
seriously, riding in the drops is way faster.
Alan Feekery - GTN did a video about being in the hoods vs drops vs Tri just a little bit ago (guessing last week but not sure exactly)
Even though he mentioned it briefly Id also be interested in time comparison between road bike + cheap aero bars & aero tt bike as well as exactly how much it affects the run in a triathlon
I was going to say who rides on the tops of a road bike when they are trying to go fast
Clinton it’s gotta be so close with aero bars on a road bike. Probably only matters for a full Ironman.
Next week
Nike next % v flip flops.
😂🤣
XD good one
Loved the video! But I would like to see the comparison riding the road bike in more aero position
There are videos comparing in aerobars on a road vs in drop bars on a road bike, in a wind tunnel, for a user to see the difference. It isn’t on this channel, but, it’s significant. As aero as road bikes are, they’re still going to conform to uci regulations, limiting their aero capabilities, whereas tri bikes don’t have this limitation.
to be fair on the road bike , you could have been a lot more aero !. your bike position was the same on the city bike
Is your gear not available anymore? The trainiac kit?
Taren, great video! I do have a question. I just got into triathlon this year (bad timing), so all I'm doing this year is training. I'm coming from cycling and have a mid level road bike. I'm considering an upgrade to my bike early next year. Since I haven't yet done a tri, I can't say for sure that I'll love the events and want to stay with it, so a tri bike is out. I'm leaning toward an upper level (but not top level) road bike with more aero features figuring that it'll serve me well next year when I start doing some triathlons, and if I end up not really enjoying them as much as I'm hoping to, then at least I'll have a sweet road bike to enjoy. In either case, the mid level bike would be relegated to trainer and foul weather duty. If I really love triathlons, then I'll look to add a mid to upper level tri-specific bike in 2022. Does this sound reasonable?
If I can choose, I would get aero road bike.
Question: If a tri bike is such an advantage then why don’t road cyclists use them? Too uncomfortable for day after day doing 160km?
It would be interesting to compare the data even with the road bike but with aerobars and good aero position. 😊
It would be interesting to see the difference between a road bike and a tri bike with a proper racing position and not a « mailman » position...
No one sits that much upright on a roadbike...and down with the head on the TT bike
This!
The problem with aero testing is that it can't take drafting into account. Cyclists were surprised when a triathlete beat everyone in the Zwift race they held at the beginning of lockdowns, but it didn't surprise me that someone that is accustomed to not being able to draft won a race in which drafting wasn't a factor.
If it’s a flat course, and you’re riding a fixed gear with the proper gear ratio, why are you going to be significantly slower than the road bike? Road bikes weigh at least a pound or two more because of all of the extra stuff, so even if you have a steal fixed gear and a carbon road bike, they’re going to be similar weights. With drop bars, they’re going to be equally as aerodynamic.
Thank you.
Something dodgy going on, the faster you go the more drag plays a role, and yet on 210W the road bike was less slower than on 150W.
Perhaps a gust of wind slowed him down, or he had more traffic passing him earlier on in the day, negating wind resistance. Basically a pointless test for gits and shiggles, which he mentioned at the beginning of the video. :D
I'm a bit surprised that the difference was less when the effort increased. I'd like to see a follow up at an even higher effort level to see if it was a fluke or a trend.
Not that great position on TT bike
You can get an aero road bike with Clip-ons very aero without spending a ton of money. Comparing a highly optimized TT to a highly optimized aero road bike with clipons would be interesting.
Learning from my past mistakes of always buying pro athlete equipment pre my first race .... I will use my existing road bike with aero bars :)
I love that experiment! Irrespective of how scientific and genralizable it is I have wanted to see something like this for a while. I plan to redo it on my favouroite 30km TT track using my current (entry+) level road bike (with TT bars though) and using the high end Triathlon bike I just bought. Let us see if I can get the About three to four minutes for the hour as well.
and, what are the results?
@@danielvalenzuela7 Using the same power, I got something like 2.5k per hour faster. However, that includes also upgrading tires and tubes from "puncture-proof and super slow" to "super thin ans super fast" as well as a 2.5k EUR disc wheel. So the difference is significant but I think you will get most of it from using better tubes and tires as well as clip-on aero bars if you start with a road bike.
Thks. Always enjoy your videos. 5% gap between the 2 bikes is not worth the spending for amateurs.
This is my first road ruclips.net/user/postUgkxMesz3KOGEmwmvyKQfLfrRSUXLFzfVHZA and I have taken it out a handful of times and so far it is exceeding all of my expectations. I didn’t want to break the bank on a first bike and the herd is a great option for getting a fast bike with reliable components. I plan on riding this bike for many years to come. Thank you Sava!
I'm considering get some clip on aero bars for my bikes... I would love to see a comparison using the triathlon, and road bike with some aero bars. I also want to see if using aerodynamic water bottles have some effect with speed.
Be really appreciated if you looked at the red-shift seat system with clip-on aerobars. Be curious to see what $300 dollars does.
EDIT: You are looking physically healthier.
I have red-shift, rode 5:20 in texas and feel the predicted time from bestbikesplit.com was accurate. I think i lost maybe 7 mins over an ironman if i remember correctly.
I just bought a $100 s.s. commuter bike for my first Sprint. This video is great. Thank you.
Great vid, agreed not scientific but very interesting. I only have a 2nd hand tribike, and with my first IM coming up it's been a learning curve! Hoped I'd benefit from only having the TT as I'm in the right position More of the time, am well used to the position and I'll take the 20 minutes benefit all day long! At.my speed a TT bike is going to knock the equivalant of 10k off the bike distance - I LOVE that!
Will get a comfy bike soon though - with an engine.
Actually, the Time Slower to 150 W and 210 W are: Sprint - 01:56:550 (150 W) and 01:37:971 (210 W) , Olympic - 03:53:100 (150 W) and 03:15:944 (210 W), 70.3 - 08:44:475 (150 W) and 07:20:872 (210 W) and IM - 17:28:951 (150 W) and 14:41:745 (210 W).
I would love to see a triathlon where everyone has the same entry level Walmart bike for maybe 10 miles.
Thanks for this... helpful. I’m sticking to road bike for now. Used it in Placid, it worked. I’m not out to break records or win. I just don’t have room for another bike!
Interesting experiment Taren! I think the next challenge should be a sprint triathlon on the city bike 🤔 have a great day!
I'm thinking of moving away from my TRI-Bike and onto an Aero Road Bike. A lot of my big races are very hilly (10,000ft across an IM), so I think it negates the advantage of the Tri-bike.
I'm also much faster and more condifent at descending on a bike with drop handlebars (I still descent like an old lady though ;) ), also favoring a road bike. I would definitely consider a road bike with clip on bars for the flatter parts for such a circuit.
what about an old TT bike vs a newer road bike? I have an old Cervelo P1 TT, and I'm deciding to buy a new road bike, the problem that I will need to solve is whether the new one in carbon, newer components etc etc could be faster than my old TT. thanks !
The bigger benefit of a TT is the body position not the frame
Maybe if I win the lottery one day I could afford a tri bike 😂
I wish you went a bit more scientific on this. Would appreciate some scientific backing on some of the facts you were casually throwing. This video is kinda obvious so where's the interesting stuff?
You didn't source a single study or research...
That was for FUN - he said .
Clearly said it’s not intended to be scientific just a quick comparison. Lighten up and have some fun. Stay safe. 😁
I would have expected a greater difference between 150w and 210w, because wind resistance raises exponential. Or I may be wrong?
IT is actually the other way around: you need a lot more power to go a little bit faster, 8 times more power to go 2 times as fast. From very coarse estimates, the required power to ride at a certain speed increases with the cube of the speed (P=C*v^3, P for power, v for velocity, C for a fitting constant). The other way around, speed increases with the cube root of power (v = cube_root(P/C) ). Increasing power from 150W to 210W is a 40% increase in power, which would result in an approximate increase in speed of 12%.
Checking with the data:
- Road bike at 150W goes 29.7kmh, 12% faster is 33.3kmh, measured speed at 210W is 33.5kmh.
- Tri bike at 150W goes 31.2kmh, 12% faster is 34.9kmh, measured speed at 210W is 35.1kmh.
These maths seem to give pretty reasonable answers with high school level physics.
This is all lovely, but what is difference when you ride 90km/180km on a hilly course? I’m a beginner triathlete so I would guess you don’t get the tri bike benefits going uphill?
what happened to the 3rd bike you tried
Maybe one day I'll get to use it
Taren, next time compare road bike riding on hoods not rails with tri bike. Your most aero position on road bike and then measure time difference.
150W "easiest pace"... lol
Taren have you ridden a P5X? Curious how much faster it is than the Ventum
Tri bike or aero bikes should start pulling off more at higher speeds or watts. But in your case road bike is closing the gap when you move from 150 watts to 210 watts. Could there be something wrong with your calculations?
Top video, but I think it's not quite balanced. Higher power should be used. Resistance to selling is exponential with speed. The gains of the TTbike would be much greater by producing a more difficult effort, probably close to 10%
Also relevant to mention that not everyone can average the same power in both bikes. For instance, I average 10 watts more on road bike (madone with medium profile wheels) in a ride similar to IM 70.3 with 800 m altitude gain, but average speed is higher on my TT (speedmax with high profile wheels) for circa 1.5 km per hour
I like this experiment, I was going to try this myself. But my road bike (with clip-ons), got stolen outside of my house, whilst drying in the sun after a wash. However, I will try the helmet experiment later this month. And possibly the Nike ZoomFly 3 vs the Nike Peg37 with HR @ 150 & HR @ 170
Just a curious question is it possible to used a dropbar on a traithlon bike?😄
Would be interesting to see the difference between an adapted road bike with dropbars, etc. and the tri-bike. Because having yo buy 2 expensive bikes is what I'm mostly afraid of as a potential hobby triathlete. Did my first triathlon on Brompton and I was still able to compete with the better triathletes (34min sprint), so I assume that I could be a good triathlete with the right bike and a bit of dedicated training.
I like the idea of this comparison, but you also switched from regular helmet on the road bike and an aero helmet on the tri-bike. That will also affect the results. I forget the actual results from your video about that, but there's still a difference. Science isn't mad, just disappointed.
Used my mountain bike for my first tri... Was the hardest thing I have ever done. I was thinking since it was heavy the downhill would be easy, however all the roadies flew by me lol.
Less than 20 minutes on a full IM isn’t that big a penalty when you consider possibly a better run it may be a wash. I’ve bee considering a high end road bike vs my mid grade tt setup and racing more hillier courses.
Great vid again Taren. I'm actually deciding what bike to use for the Montreal Esprit Sprint Triathlon next September. The ARGON 18 E112 with a full disk in the back or my road bike TREK EMONDA SL6? I think I'll go with the ARGON. An Idea!!! What if you redid the test but with speed as your constant. You could pick a speed like 30km/h with the three bikes and compare POWER and HR for the same speed. That could also be quite interesting. Just a thought... Ride on!
Hi Taren. I would love to see the difference in run times for, say 5km, following riding the road bike for 20 mins and then the tri bike for 20mins. I would believe that I am more comfortable on the road bike and hence would run faster following riding on the road bike
I did an ironman once on a rented road bike. Got off it hardly being able to walk. I thought that I will have to walk the whole marathon. Took like 10 min before I could attempt to jog.
A better comparison might be road bike using the drops or aero bars to the tri bike. I suspect the difference will be a lot less. Maybe also with red shift seat post or other post to change the hip angle in line with a tri bike.
I think beginners see it as crazy to spend the money on a tri bike for only a 3 minute difference and experienced athletes see it as crazy to not spend the money for 3 minutes. I started on a road bike which I think is the perfect place for people to as well.
You have have at least used the drops...who time trials on their hoods? 😏
Hey Taren,
Thanks for the great videos. Would love to see the clip on tri-bar comparison.
Can the less aggressive hip angle on the road bike be beneficial on the run if you are doing your best effort on bike portion ?
But that's only on flat roads, it's different agan if there is elevation...
How long do you need to train to feel that 150 watts is easy?
Next video- speed increase using cheap aero bars on a road bike vs. Tri bike
Orrrrrr...you just buy one of each kind of bike. Lol. N +1
Haven't watched the video yet so it might be explained, however;
If the tri bike is so good then why do cyclists not use that style bike in the TDF etc? (excuse my ignorance, I am a runner looking at maybe doing tri in future)
Because they are against regulations, and while a TT bike is great on the flat you would never want to climb mountains with one.
Surely this depends entirely on the position of a given individual on both bikes?
Great video and answers to the such question
Should use the same wheels on road and tri bikes
It would be more relevent to chuck a set of aero bars on the road bike, and then make the comparison.
And by adjusting the saddle position and sliding it forward, maybe this would assist in making the legs more ready for the run???
That’s not a huge difference for the weekend warrior.
position on rb is off though
you should do the fat bike!
Time Trial. Not Tri Bike.
Would it also make you faster on road bike riding drops?
Yes, lower and more aero
I just wanted to know what bike will level me faster on zwift
E-bike
Great video,
What about completing your first 70.3, is a road bike OK?
Yes, see a bunch of people on standard road bikes, Winthrop and without aero clip one.
@@rudgore awesome, thanks for replying. Not sure I;m ready to upgrade yet.
Hi Andrea; did my first 70.3 on a road bike and went great (was just doing for the experience and not time) so much so that for my 140.6 I stuck with the same bike (again just looking to finish not hit a time). Unless you're competing and/or need the faster time, the road bike should be able to meet all your needs
@@chadhossier12 that's great info! Yeah I've done all sprints and was suppose to do my first Oly until Covid hit. I want to just finish a 70.3 without receiving a DNF.
I did, no aero bars. My run suffered a bit. It's easier to transition off a tri bike, but if you're just looking to finish mid pack, who cares?
The tri bike looks stupid af.
