These shifters work great, they feel good in hand, on the hoods & aero hoods positions despite being made ergonomically smaller for smaller hands. I used an old Claris setup before & the tops of the hoods were massive & easy to grab with 3rd & 4th digits. The Ultegra shifters shift with an audible snap & simultaneous shifting action at the rear mech. These are absolutely fantastic, hope to do many miles on them.
These function as flawlessly as you would expect and look amazing of course, if I could afford Dura Ace I would buy it but everything I've read suggests I wouldn't be able to tell the difference anyway. I definitely love the increased reach adjustment, I have relatively small hands so being able to get my fingers around the lever while in the drops is very reassuring.
