Chorus 12-speed adds the wide 11-34 to Campagnolo's 12-speed line-up, giving more choice and autonomy for climbing, while keeping the same wheel and frame fit as 11-speed.

Highlights

  • Same width as an 11-speed cassette
  • Two larger triplets as single pieces
  • Surface treatment for durability and smoothness
  • Same-thickness spacers for error-free fitting
  • 11-34 option for climbing

Gearing

Both sizes share single-tooth steps from 11 to 17. The 11-34 swaps the final triplet for 25-29-34 for easier climbing gears.
