I have been lurking for a couple of years and notice a ton of threads about aero wheels, aero brakes and “super bikes”… How come aerobars aren’t often discussed/debated?
Is there already a consensus on the best ones that I have missed?
Do get me wrong, I do see info about aerobars here and there in threads, but it’s typically an after thought.
There’s a lot of fast aerobars. Just like many superbikes, they lack adjustability in terms of extension tilt, have too much stack, limited stem lengths, and cost an arm and a leg.
The big take away from the data is that if you pick a decent base bar and add clip ons to it, you’ll be with a few watts of the most expensive set ups. Applying the the data from the graph, if I used the Felt Bayonet 3 bar and clip ons with my position I’d be 0.7s/km faster than if I were to use the 3T Ventus despite the Ventus being more aero by itself.
There are a few bars that are known to be really really good:
3T Ventus
Zipp VukaStealth
USE R1/Tula
TriRig Alpha with the TriRig stem
Shimano PRO with their stem
3T Aduro (you can hack this onto other bikes than the p5)
Getting a slick cockpit on a bike is a big part of the equation. It can turn a P2 into 99% of a P5
In terms of the actual aerobar used, the consequences on aerodynamics are fairly minimal. Rider comfort and rules (e.g. if you’re under UCI rules) come first.
As you can see, you can lose a significant amount of drag by going from “meh” such as the Zipp Vuka Alumina to best of breed based bars… all of which are “close enough”.
