Wheels Manufacturing Derailleur Hanger #513 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

Confirmed fitment per Wheels Manufacturing / SCV:

  • Thread Pitch -M12x1.5 - Rocky Mountain: 1811003, Hanger 29 - This hanger has M12x1.5 axle threads. For M12x1.0 axle threads see DROPOUT-587

Derailleur hanger fitment is frame- and year-specific — match Hanger #513 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. For warranty support, return the product to Tune Cycles and we'll manage the claim with Wheels Manufacturing's Australian distributor.
