Shimano Ultegra CS-R8101 Cassette Description:

The Shimano Ultegra CS-R8101 Cassette utilizes Hyperglide+ technology allowing for better shifting under load so it is no longer necessary to ease up on the pedals when making a shift. For simple compatibility, Shimano 12 speed road cassettes fit on the same hub body as 11 speed road cassettes. This allows riders to use their current wheels for 12-speed. Shimano also managed to add the extra sprocket without increasing the total weight of the cassette.


Features:

  • Refined 12-step gear combination provides maximum efficiency and accelerating performance
  • Compatible with 12 speed Shimano Di2 and mechanical shifting systems
  • Compatible with 12 speed and 11 speed freehub bodies
  • Faster, seamless shifts under maximum pedaling load

Specifications:

  • Type: Cassette
  • Speeds: 12 Speed
  • Drive Type: Shimano HG (11/12 Speed Road)
  • Color: Silver
  • Weight: 291g (11-30T) 345g (11-34T)

Sprocket Configuration:

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

Casette actually came with the spacers in the wrong order! Not sure how that happens, but I after my race had to disassemble and rebuild it correctly. Works fine now
