Overview

What bikes does the Wheels Manufacturing Derailleur Hanger 431 fit?

The Wheels Manufacturing Derailleur Hanger - 431 is a direct replacement hanger for Co-op Cycles REV 20, REV 24, and REV DRT bikes from the 2019 through 2023 model years. It attaches to the frame with one long 8mm chainbolt. If a bent hanger has the shifting going sideways, this is the part that puts the derailleur back in line.

Each hanger is CNC machined from 6061 aluminum in Wheels Manufacturing's Colorado shop and finished in black anodize. It is built stiffer than almost any OEM hanger, which improves durability and shifting. The hanger is designed to bend or break before your frame or derailleur does, so a spare in the garage is cheap insurance. Compare the shape to your current hanger before ordering, since bike brands sometimes change hangers mid year.
