ERGONOMIA ULTRA-SHIFT Ensures a firm grip on the handlebar and fast, precise control of the levers. The special ergonomic design allows three different hand positions on the levers compared to the traditional two. NEW VARI-CUSHION BRAKE LEVER COVERS WITH VARIABLE DENSITY AND SURFACE FINISHES Natural silicone material with differentiated areas to follow the grip of the 1st and 2nd fingers. The grooved areas drain water, keeping the brake lever covers dry and improving grip. Internal weaving creates a variable thickness that ensures maximum possible comfort. ULTRA-SHIFT MECHANISM WITH MAXIMUM NUMBER OF DIFFERENTIATED UP-SHIFT CLICKS BASED ON THE STARTING SPROCKET The only mechanical group on the market that allows multiple shifts (up to 5 sprockets). Quick positioning on the desired combination in case of a steep gradient increase or near a curve (up to 4 combinations with chain on the first 4 sprockets, up to 3 combinations with chain above the fourth sprocket). BRAKE LEVER CAPS AND CABLE HOUSING ARE AVAILABLE AS SPARE PARTS IN RED AND WHITE CABLE ADJUSTMENT BAR Allows perfect adjustment of the derailleur cable tension, drastically reducing adjustment times.
