This, patent pending, aero extension is made of full carbon construction with an integrated shift boss weigh ing in at a mere 65g .By eliminating the expansion system required to install standard bar end shifters, and integrating the mounting boss into the bar construction, we have been able to eliminate 30mm of length from the end of the bar. What this means to the rider is no more cramped wrist positions! And no more getting out of aero position just to shift.

 

For such a small product, this will make a really big difference at the end of your ride. Whether it is your local sprint, requiring many shifts, or your favorite 112 mile stretch of road, followed by a little jog. Your wrists, and bike splits will thank you.
