Just installed the Easton Attack TT bars and spent my Sunday dialing the fit in. Man what a difference! Compared to my old set up, Deda Aerodu with HED race bend extensions and Profile F-19 arm pads, I am both more aero and more comfortable. I haven't ridden this bike since June and after some minor tweeking I did a 10k full TT effort and felt really comfortable doing it, no sliding around on the saddle trying to find the sweet spot just settled on and rode.
Great bars...if they fit your position. I'd love to have a set but I'd be nervous about not being able to adjust the extensions.
Yeah that's a big issue when paying retail for them, luckily I got them at pro deal pricing so the hit was minor. If they didn't workout for me I could have ebay'd them for much more than I paid for them. They do happen to fit me perfectly with the added bonus of looking damn good as well.
