This is the Ultegra CS-R8101-12 in the 11-34T spread: twelve nickel-plated steel sprockets running 11-12-13-14-15-17-19-21-24-27-30-34T. It uses Shimano's HYPERGLIDE+ shaping, which is designed so you can change gear under full pedalling load, even during a hard effort on a climb.
The 34T low gear suits hilly roads and long days out, while the close steps through the middle of the cassette help you hold cadence on rolling terrain. It fits Shimano 12-speed and road 11-speed freehub bodies, so many existing wheels can take it, and it needs a 12-speed HG chain.
Road riders on a 12-speed Shimano drivetrain who want a 34T low gear for hills and long days.
