Despite being excessively combative at times, Karla knows his stuff. If he and I have differing opinions regarding cycling, I often reexamine my justifications to check whether my opinion is reasonable. Sometimes my opinion stays the same, sometimes it changes.

Seconded.  To get the most value from this thread you should probably delete all the other bits and just read what Karla has said.  A little bit of input from someone who knows a lot about the subject is worth a lot more than enthusiastic comments from those who know less!

Zero direct experience, but the wrist angle in that third picture is painful to even look at.

And contrary to what Karla says, if you’re *shopping* for aero bars the flatter style seem to be significantly more common.



When you look at the pro's they tend to have the flatter bars. But that is because they have wind tunnels and all that matters is the most aero position they can hold for about an hour. A lot of people who wanna look like a pro, thus have the flat bars. Thus their popularity. It's a really uncomfortable position for the wrist.

When you look at photos of ultra racers, their bikes tend to have the sky jump or J bars. Cos it's more comfortable.

I have no idea about UK amateur TT riders.

Do people find flatter clip-ons less comfortable? I've never tried them.

Less comfortable than the fully integrated base bar and setup? I think it all depends on how much you can adjust the fit. If you can get the fit right for you, then there is no reason you shouldn't find both comfortable. But it's a big if you can get the fully integrated setup to fit properly for you.

It would be natural to assume that pros have more aero positions that amateur UK time triallists. But they don't.  It's a common discussing point on the TT forum how unaero many pros are.

There are various reasons for this. Firstly time trialling is a UK thing, for historical reasons. So we have a community of people who race up and down dual carriageways every weekend. This doesn't happen anywhere else. Most pros are not TT specialists. They actually hate TTs. The last thing they want to do is compromise their road riding position, which is central to their job, to get better at TTing, which isn't. So they don't.

Even some pros who are good time triallists have pretty poor aeros. Armstrong is a good example. What they do have is loads of power which they can use to compensate.

If you want to see what is best in aerodynamics, don't look at pros, look at the kimroy link!
