FIRST: disassembly tools

Fixed ratchet disassembly tool

The fixed ratchet ring is screwed into the shell of the FIRST hub. This tool is essential for disassembling it.
It can be used in three different manners:

1. With its slot for an open-end wrench.
2. Clamped in a vise, with the hub attached to the tool, using the complete wheel as a flywheel to apply torque for unscrewing.

3. With an impact wrench: ideal loosening torque >800 N·m for sport e-bike wheels, and >500 N·m for road/mtb wheels.

Axle Holding Tool

The wrench slides into the axle on the disc side and holds it via its lugs, which fit into the notches on the axle.
It is ideal for securely holding the axle without risking damage to it.
