The ultrafluid experience of the 12 -speed Ultegra R8100 range allows you to overcome climbs, sprint and take long travel without stopping to think about the next gearbox. The larger pignons maximize the efficiency of the transmission system and create compatibility with the Shimano 11 and 12V hub bodies.
The Hyperglide+ cassette revolutionized the gearbox in off -road vehicle with a perfect fluidity of change and climb. The time has come for technological changes for road cycling. Even during the maximum uphill efforts or competing with a friend, it is no longer necessary to reduce the pressure on the pedals to change gears. In any march, the Ultegra R8150 transmissions maximize efficiency thanks to larger pignons and maintain compatibility with the bodies of the existing Hyperglide rear hubs. All this passing to 12-speed and without increasing weight, the ULTEGRA CS-R8100 boxes are the new frontier for road bikes.
