Derailleur hanger fitment is frame-specific: hangers that look alike are often not interchangeable. Match this hanger against the derailleur hanger currently on the frame (or the frame's exact model and year) before ordering. The Tune Cycles workshop can fit and align a new hanger — derailleur hanger alignment is a workshop service.

Wheels Manufacturing backs this hanger with its published 1-year limited warranty against manufacturer defects from the original date of purchase. It excludes normal wear and tear, damage from crashes, abuse, misuse or improper installation, and proof of purchase is required. For warranty support, return the product to Tune Cycles and we'll manage the claim with Wheels Manufacturing's Australian distributor.
