The CS-R8101 cassette, shifts faster and smooth. You can shift gears without hesitation even when exerting maximum force on climbs or sprinting to the finish line. This is made possible by a slightly optimized tooth profile.
Shimano also uses Hyperglide+ technology, which has proven itself in the off-road sector. This significantly reduces the time required for both upshifting and downshifting and, compared to conventional HG systems, enables smoother pedaling.
Despite the new design and the additional 12th sprocket, the CS-R8100 cassettes are also compatible with previous 11-speed Road freehub bodies.
