Use 12mm wheels in a 15mm fork. Converts 15x100 forks to 12x100 standard! Kit includes the following:


• Thread adapter: M15x1.5mm pitch external thread, 14mm long, M12x1.5mm internal thread

• Thru Hole Insert: 15mm OD x 12mm ID, 10mm long

• Axle: 12mm x 130mm long, M12x1.5mm threads, 2mm spacer (optional, for fine tuning length)

Installation Notes:

1. Use either grease or low-strength threadlocker on thread adapter

2. Use Park Tool SPA-2 or equivalent 2.3mm pin spanner to tighten thread adapter into fork. Flange goes on the OUTSIDE (see third picture).

3. Use grease on o-ring of thru hole insert and install into fork from the outside with a combined pushing and twisting motion. Do NOT use thru axle to drive thru hole insert into the fork.

4. Use grease on threads of thru axle. Torque 9 - 13.5 N*m using 5mm hex.
