Braking is one Ultegra 6800′s major advances, evidenced by the inclusion of a revised, standard caliper, and front and rear aero brakes, for which Shimano has also produced 105 equivalents (that’s the BR-5710, part code fans). The Ultegra aero brake has direct mount options for fork (front) and chainstay (rear) and claims for increased modulation.
Ultegra components offer an ideal balance of light weight and stiffness, making it the perfect choice for both enthusiast and competitive riders
