Wheels Manufacturing Derailleur Hanger #662 is a direct CNC-machined 6061 aluminium replacement for the sacrificial hanger that bolts the rear derailleur to the frame — the part that's designed to bend or snap in a shift-into-the-spokes crash so the frame and derailleur don't have to.

Compatibility & fit

Fitment, per Wheels Manufacturing:

  • Fits Look frames that use Look hanger part #00023431
  • M12x1.0 single-lead thru-axle thread. Hanger #663 is the double-lead version, so check your axle thread before ordering
  • Attaches with one M3x15mm flat-head screw and a custom locknut

Derailleur hanger fitment is frame- and year-specific — match Hanger #662 against the old hanger (or the exact frame model and year) before ordering. The Tune workshop can fit a new hanger and align it on the bike; derailleur hanger alignment is a workshop service, not something to skip after a hanger swap.

Covered by Wheels Manufacturing's 1-year limited warranty against manufacturing defects from the original date of purchase. It doesn't cover misuse, normal wear and tear, incorrect installation or crash damage.
