ULTEGRA R8100 - LEAVE TIME BEHIND

When developing the Ultegra R8100 series, Shimano took a holistic and 100 % performance-oriented approach, because great speed means great responsibility. Faster than ever before, the 12-speed road groupset scores with unparalleled control and comfort anytime and anywhere - whether in an everyman race, on the hunt for a personal best time or on a companionable ride.

As with the Dura Ace R9200, not only does Hyperglide+ make its way into the Ultegra's components, also its Di2 parts rely on Wireless technology to simplify operation and ensure smooth shifting.

SHIMANO ULTEGRA CS-R8100-12 CASSETTE

The Shimano Ultegra CS-R8100 cassette is characterised by seamless shifting processes that not only ensure quiet cruising, but also allow the rider to devote their full concentration to climbs and sprints. 

Hyperglide+

technology which has already been able to convince in the MTB segment with smooth shifting processes in both directions across the entire gear range.

Even under maximum effort or in a direct duel with the opponent, smooth upshifting and downshifting can be realised, while larger teeth maintain maximum efficiency. And the 12-speed cassette is even compatible with Shimano's previous 11-speed freewheel bodies.

Sprocket ratios:

• 11-12-13-14-15-16-17-19-21-24-27-30 teeth
• 11-12-13-14-15-17-19-21-24-27-30-34 teeth

HYPERGLIDE+

The conventional Hyperglide technology ensures smooth shifting upwards thanks to small shifting ramps, which guide the chain towards the next larger sprocket. Also Hyperglide+ uses this functionality but applies it in the opposite direction, too, preventing the chain from falling down when shifting downwards. The result is a smooth and consistent shifting in both directions, free of vibrations and without disrupting the cadence.

Material:

sprockets: steel (nickel plated)

spiders: aluminium (anodized / painted)
