Aero Vs Climbing Bike - The REAL Difference Wind Tunnel Tested

In the bike industry at the moment lines are being blurred between lightweight and climbing bikes. We build two bikes up identically, one aero and one climbing frameset to find out how they differ. Thanks Scott for supplying the frames and Aerocoach for having us at the wind tunnel.

The more hard data I hear about losing 2 watts here and there to save like 30 seconds on a ride, the more I just want to pick my bikes based on how cool they look.

[@Xarx42]

Why not? And even if you are just marginally faster having the aggressive and direct feeling (or the oppositve, whatever you prefer) certainly contributes to the ride. :) Ah, as long as you are happy with the sporty position of an aero bike... ^^

[@Nowayfrrrrrrr]

The best bike is the one you like because it makes you ride more

[@Mike0]

You could save 2min over an IronMan distance bike (although 1kg extra weight would cost you 1min)

[@HarryFunmaker]

Props for testing at speeds that are relevant for us mere mortals. I still prefer the looks and feel of a lighter bike. I don't care if it's a few seconds slower.

[@jrasero23]

I think the problem is the same problem the Addict had when the last gen Scott Foil RC was around in that the Addict isn't that "light" for a climbing bike and two the Addict with the Syncros cockpit and a good set of aero wheels is aero enough that most people confused it with a last gen Scott Foil RC, thus this why Scott for their current gen Scott Foil RC made it drastically different and also tried cutting the weight. The fact of the matter is that the Addict is pretty long in the tooth gen wise since it's in this odd spot. I have a 2022 Scott Foil RC that weighs 17.13lbs with pedals, cages, and mounts and a 2023 custom Specialized Aethos Fact 10r at 14.72lbs with pedals, cages, and mounts, so right there that is a better example of a true climbing bike versus aero bike not only due to the 2.41lbs difference but because the Aethos's round tubes and more compliance.

[@TaylorRoss-g7o]

Great video and interesting insights. Here's my experience with both bikes. I have an Addict RC 15 (Ultegra Di2 24 speed) and the same finishing spec on custom build Foil RC 2023 (using Ultimate RC frame). Both bikes with Ultegra C60 wheels. I’ve had my Addict for a while and it’s been a great bike. This summer, I got curious and decided to build the Foil. I put the new bike through the paces and it blows my mind on every kind of ride (climbs, fondos, etc) I am not a racer, nor a climber but I smashed through hundreds of PBs and segments in the last few months. I find the Foil more comfortable, more agile and mostly feeling safer on the pothole-ridden South East England roads. It looks like a tank but it does everything with ease. I was very happy to be in Team Addict but the Foil converted me to the other side.

[@mvhan911]

So the foil is more comfortable in your opinion in contrast to the statement here in this video? I find it interesting that about every aspect there are other judgements.

[@DG-tf9rp]

The best, honest, Aero/Climbing bike Vid I have ever seen. Keeping all things equal except for the Frame is the way all comparison Vids should be done. Great job.

[@eis_baer918]

yes, sort of. but to make it complete, I'd also include the wheelset. on an aero bike you'll probably put decent 50mm on (around 1500-1600g) whereas on a climbing bike, i would rather put on ~30mm but lighter (~sub 1400g) wheels on. which probably extends the difference in both directions. but still, in the end I would take the more comfortable bike. which will be the climbing bike.

[@renatab8293]

I live in the Colombian Andes at almost 3000 metres. The thing everyone forgets is that the air (especially oxygen, which is heavier than nitrogen) is very thin in the mountains, so there is less air resistance, less aero penal and therefore ...less aero advantage to an aero bike/position/set-up. Even on flat roads you go faster here by sitting up straight because getting oxygen in the lungs is the big challenge, not pushing through the air which offers less resistance here. So how you should ride in HILLS is not the same as how you should ride in MOUNTAINS, two things many Europeans confuse.

[@greg_one_izm]

thats the exact thing everyone mentions when talking about training at altitude... I've never met anyone who "forgot" that the air is thin in the mountains... o.O

[@renatab8293]

@@greg_one_izm "I've never met anyone who forgot that the air is thin" Well, there are all the people who have bought aero bikes - the bike shops in Bogota, Cuzco and Quito are full of them, so are the roads. Also, all the people who adopt an aero position on their bike, even though it is slower here because the there is not enough aero penalty. In fact, I would say well over 95% do not realise the consequences for cyclists of the air being thin.

[@greg_one_izm]

@@renatab8293 on the contrary, just because the air is thin, doesn't mean there is 0 benefit from an aero position... Maybe some people feel more comfortable tucked than not, maybe they're simply fit and flexible enough that there is no downside to sitting in an aero position for them.. Maybe they feel more stable in the drops than on the hoods so it just appears they're trying to be aero when in actual fact they're just doing what they enjoy/like.. There's more to a bike than just pure efficiency, sometimes we wanna ride a lambo and feel cool for a while lol

[@buggen819]

I thought of buying a aero bike a while ago because I thought they were a lot quicker but this really makes me stay with my normal race bike.

[@JackMott]

The frame alone is a small detail. But the frame, plus the cockpit, plus your helmet, plus your skinsuit, plus the wheels, plus good tires, and so on. Adds up to a lot. So start with the biggest bang for the buck (tires, clothing, helmet, cockpit, wheels). Frame is last.

[@NisseOhlsen]

how fast do you ride? Most sportive riders would stay well above 30 km/h for long and then the advantage, measured in watts, for the aero bike is huge, in this case. Scott needs to update the Addict. It's essentially a year 2021 bike.

[@Pablo_Coach]

@@NisseOhlsen position on a bike (ability to sustain aero position) is a key not frameset

[@CycletheNation]

I'm genuinely surprised at how little the difference is across the whole spectrum really (weight, wattage losses), but secretly(?!) pleased. I bought a Giant TCR based on weight, as I knew they were light as standard. Living here in the Lake District, weight is a big factor for the steeper hills (especially for something like the Fred Whitton). However, it's still compliant and comfortable enough to use as an endurance bike as I demonstrated on my challenge back in June when I did 1142 miles in 8 days. I'm fully intending to use it on a (not flat) 24 hour endurance ride this year too. I'd been considering aero bikes but this has concreted my beliefs (based on zero facts) that I would be wasting a lot of money buying one, when an endurance bike is so similarly matched.

[@thetinusnl8834]

TCR all the way. I live in the incredibly flat Netherlands and I still chose a TCR over a Propel because the Propel was much more expensive, but has the same geometry. Those like what, 3, maybe 5 Watts at mere mortal speeds are not worth spending hundreds of euros on a different frame and/or wheelset. Defy doesn't have the aggressive geometry which I wanted, plus it was priced identically, making the TCR a no-brainer. Especially considering its price compared to other brands. I still have to find out how the TCR does on super long rides, but I could always take my gravelbike and slap on some slicks...

[@SimonGoesSideways]

Great video lads ! I think it was perfect that your tests were done at 150w on the road and 30kmh in the wind tunnel. It is the power/speed an average road cyclist would ride at. There is plenty of data out there for these bikes at 45kmh but that speed only applies to pros. A normal person would only reach that speed going downhill or sprint to the town sign.......never as an average. So bottom line is, for a normal, recreational rider, don't worry about the numbers, just buy the bike you like and the one that fits you best.

[@littlevo9]

I'm a long time viewer of the channel but this is the first time I've listened to the podcast, while I was fettling and cleaning my kids bikes! I enjoyed it! (The podcast, not so much fettling the bikes). This country could benefit enormously from some nationwide education for drivers.

[@MrJohnnyTN]

lots of commenters are missing the point.. stuck on semantics of calling the addict a climbing bike, wanting to compare to rim brake, on and on. I should be shocked but I'm not. Good test guys . Super rare to have bikes setup with same stack height and components. 30kph is good solo riding pace , but I would expect 3.7w would more then double at 40+. Not everyone races and I can respect that, but 40+ is what interest me. I'm choosing the Foil

[@dropin324]

Great comparison of two types of road bikes. As someone who is new to drop bars (only ever had tri bikes) this helped me determine that I want a climbing bike for my first road bike.

[@daevion5585]

As a sucker for aesthetics, I'd take the FOIL. But as a literal sucker on climbs, I'll take the ADDICT... or a motorbike.

@@rudySTi for someone who’s not concerend about weight yes, but not when you are a climber and pay a lot only because you want a bike that‘s lightweight. 500g is like the difference of ultegra and 105. and in competition and racing (which I do) it‘s definitely noticable. So it‘s important to me. Everyone has his/her own opinion and that‘s ok.

[@rudySTi]

@@Nicuu98 If you are a pure climber and do that mostly then I see your point. But on flatter terrain 500 grams is not an obscene amount. TDF bikes are 7.35 kg on average even though the limit is 6.8. If 500 grams were that big of an advantage you would think most riders would hit that dead on. Also the bikes mentioned in the clip are middle of the pack when it comes to price ranges, therefore you would assume they are not being used at the absolute highest level.

It sounds like the sprinting performance might be a reason to go with the race bike for racing -- if the frame can handle 1500W or whatever without losing some watts to flex, that might really matter for final race results.

Exactly. My aero bike goes faster when sprinting out of the saddle and also standing up on climbs. It may be a bit heavier but it goes quicker.

Well, I have the S-Works 2020 Venge aero road bike and it's jaw-droppingly light & fast. It's a rim brake version (last one ever made), and it weighs under 15 pounds, so around 6.7 kilos. So with this road bike, I have both a weight advantage, and an aero one. It's savage. My FTP isn't even that great but when I'm on this bike, I'm brash and peppy! I like it a lot.

I live in Los Angeles. While much of the area in and around the city is flat, there are a vast number of steep roads. For now, I’m hanging onto my all mechanical 2017 Trek Emonda, which is well under 6.8 kilos, with pedals. The major upgrades I’ve made are an aero set of wheels, TPU tubes, and a lighter chain. I prefer the feel of my lightweight bike, even though I know a 17k or 18k bike with the latest tech won’t feel much - if at all - different when I’m pushing hard up a 15+% grade, and would only cost me a few seconds.

those apocalyptic winds are hardly "real world" riding conditions either. I'd also say that only riding at 150w isnt fast enough for the aero benefits to show. Since wind resistance increases with the speed, the faster you're going the more benefit the aero bike has. If you're only riding around at 150w it really doesn't matter which bike you ride.

Too bad we didn't get the figures for bikes differences at 40, 50 and 60 kph. Aero bikes are made to go really fast, not to average 1 minute less over 2 hour rides, hence why they are so stiff and not so confortable. The faster you go the more the gains compound.

[@Xarx42]

Large crosswinds on even picking the wrong wheels aren't much fun when you're a lighter rider.

Hey Francis, I know you don't read these but I am hoping Emily or someone spots this (rather random) question: Have you ever tested with and without a cycling cap in a wind tunnel, and does peak up or peak down make a difference? It always seems to be something missed out of the equation in these things. Gotta be worth a few watts one way or another, right?

I mean, if you really are such a road bike enthusiast, who spends a lot of time in the saddle and likes to switch things up from time to time (and if you have the money): then getting both can be a possibility. But as said: its gonna be pretty expensive, so I would think about it twice if there is really no other priority to spend your money.

Francis you should do a bmx vs roadbike climbing video. There is a guy in my town that is famous for beating so many road bikes on a bmx on a local climb.

[@danielguderian4649]

I liked it! Could you do the same thing comparing either of the bikes to a more relaxed/enduro geometry? Peace

[@Squizzy05]

Can you compare that with the addict endurance version ?

I've got a PX-EC130E and just got some Prime 55 carbon wheels and aero bars .. will be interested to see what the weight is and how it climbs 🤞

I'd never be going fast enough to enjoy the gains so it's the comfy one for me.

Addict for me, which is what I've got.🤩 but, it's the SE model, 2019 di2, love it. I think the Foil looks better, but at 69years old, when I got it, it made better sense. Still love it to bits, and I can step off it after a 100 mile ride, as opposed to having to be lifted off a Foil if I'd bought that model.😉

Addict SE is an endurance bike, id imagine you would be more comfortable than riding an Addict RC or Foil RC.

[@peterthomas8053]

Exactly, which is the reason that I chose the SE. More relaxed geometry is ideal for my aging body.😉@@JayLato

Have you had any issue with Etap overshifting the front derailleur when in gear 6/7/8?

2:42 Clamping the Scott foil by the top tube?

[@luismartinho7044]

I have a Scott Addict but I want to change it to a foil but with this video I got to thinking.
