isn't it awkward not having any arm supports?
Ive never used aero bars, but for ages I have used mtb bar ends to get lower down, and as I do use trekking bars, I could see how with these one could lean slightly on the closest part of the trekking bar to give some support while reaching out to the frontward pointing out bar ends.
I even sometimes lean on my trekking bars like this and do a "time trial" position, although that particular bike is a bit twitchy, so I have to be careful. I do this position on dropbar bikes and it works pretty well, so I can see how it could work well on trekking bars.
I guess my question is, Is it worth having these bars sticking out and in the way if you hardly ever use them?
I guess there is no clear answer to that, and I'd have to live with them for a while to see.
