Avid's flyweight X0 stoppers are powerful enough to stop you on a dime and sensitive enough to modulate you down the trickiest descents and guide you through loose, off-camber turns. With Avid's Contact Point Adjustment, as well as choose between the modulation of a longer throw or the instantaneous power of a short throw. Combine that with Avid's Reach Adjust, and you have some of the most customizable brakes around. And, perfect installation has never been easier thanks to Avid's renowned Tri-Align Caliper Positioning System. The X0 also comes spec'd with Avid's HS1 rotor.
