All components related to the drivetrain and brakes - shifters, derailleurs, crankset, brake levers, and brakes - are collectively referred to as a bike's groupset.

There are currently three major manufacturers who make complete groupsets: Campagnolo, Shimano, and SRAM.


These lists contain each major manufacturer's mountain groupsets in roughly ascending order of quality.[1]

  • Veloce
  • Athena
  • Chorus

Chorus, Record, and Super Record all have EPS variants, which shift using servo motors rather than cables.


  • Claris
  • Sora
  • Tiagra
  • 105
  • Ultegra
  • Dura Ace

Ultegra and Dura Ace both have Di2 variants, which add electronic shifting in a manner similar to Campagnolo's EPS systems.

Red offers the eTAP variant, which functions similarly to EPS and Di2, but is wireless, rather than wired.
