Usage & installation

• Replacement for worn or damaged gearbox

Important: this replacement requires basic mechanical skills. Nothing overly complex, but a solid understanding is necessary.

It is essential to leave a slight chain slack during reassembly. A chain that is too tight can cause damage during impacts (jumps, compression), as the bike flexes under load.

In these conditions, the 90° gearbox absorbs the impact and may fail. Always adjust chain tension properly to protect drivetrain components.
