Thanks. This if for my road bike and they will likely come off and on. I plan to use them for TT's, while I decide if I want to take the plunge into buying a TT bike. I'm wondering if anyone knows if there is a difference in whether the bars bend up or not as far as one being more aero. Seems like straight would be most aero. Or is it just whichever feels most comfortable to you? I have read that comfort precedes weight when it comes to a TT bike. You must be comfortable to do your best. I wonder if that applies to TT bars as well. So the next question is, do more people thing one is more comfortable than another ... cause I have no experience to draw from.

I also asked a coach his opinion, in case anyone is interested. Not the above question specifically, so he commented on brand.

He says ... "Profile makes the best clip ons. Model will depend on are you going to leave them on for centuries or take them on and off for training and racing. FYI, if you have carbon bars now you will need to switch to aluminum to put the clip ons on."

My husband's input on the carbon verses aluminum thing is it depends on which carbon bars you have. I have carbon and he is not worried about putting clip on aero bars on them. I won't be pulling up on them and he can't see anything happening to them. He's used aero bars on his before and had no issue. Has the same bars as me. He says he'll buy me knew handlebars if something actually happens to them!
