Cannondale derailleur hanger K33040 for F-Si 2020+ (hex)

Description

On the trail, all it takes is a small hit on a rock or an unexpected crash and suddenly you’re wondering why your shifting isn’t as crisp as yesterday. Cannondale patka K33040 pro F-Si 2020+ (hex) is an inconspicuous part, but it can save you a lot of frustration and time at the workshop. When the hanger is straight and properly seated, the drivetrain runs cleanly and the bike feels “like itself” again.

Main benefits

The derailleur hanger serves as the connecting piece between the frame and the derailleur, and it also acts as a deliberately “weaker” point that helps protect the more expensive parts of the bike in the event of an impact. The K33040 model is designed for Cannondale F-Si mountain bikes from model year 2020 and newer, so it fits where universal hangers often fall short. Thanks to its precise fit, it helps keep the derailleur in the correct position, which translates into smoother shifting and a lower risk of the chain dropping under load. The hex fastening also means standard Allen-key service without any unnecessary special tools.

Technical specifications

This is a replacement rear derailleur hanger marked Cannondale K33040, compatible with Cannondale F-Si 2020+ frames. It is designed for (hex) installation—mounting with a bolt for an Allen key—which makes replacement easy at home as well as at a regular bike shop. The hanger is built to match the specific F-Si rear triangle geometry and keep the derailleur properly aligned with the cassette. It’s ideal as a direct replacement after bending, or as a sensible spare to keep on hand for races or weekend rides.
