Campagnolo Chorus HO Rear Mech

Campagnolo's Chorus HO Rear Mech features a carbon fibre outer plate and jockey wheel cage and offers you shifting performance that's comparable to their higher spec Record and Super Record models. One of the stand-out features is the “Embrace” technology, which ensures an ultra-efficient chain and cassette interface, secure chain grip, increased durability, and excellent power transfer.

Disc Brake Frame Specific

This HO (hydraulically optimised) version is specifically designed for use on disc brake frames that feature the wider 12x142mm rear dropout spacing. It features an adapted mounting link for easier thru axle removal and larger teeth on the upper pulley for precise shifting at more extreme chainlines.


  • Material: Anodised Forged Aluminium (upper body) Carbon Fibre (outer plate and jockey wheel cage)
  • Multi-shifting technology allows you to upshift up to 3 gears at a time
  • Embrace technology for better drivetrain efficiency
  • Parallelogram with 11x geometry
  • Lightened special rubber pulleys
  • Maximum Cassette Capacity: 11-29T (short cage), 11-32T (medium cage)
  • Weight: 183g


Ultra-Shift™: This control system by Campagnolo is regarded by everyone as the fastest and most precise out there. With this system, you can move the chain simultaneously up 3 sprockets and then 5 down. Furthermore, the lever design allows for an ever lighter shifting, whilst maintaining the "click" sound featured on all Campagnolo® controls.

Embrace Technology: This technology increases the number of sprocket teeth wrapped by the chain, allowing smooth, fast, and prompt shifting. Proven to optimise the functionality of the rear derailleur even when using extreme cassettes such as 11-32T.
