For hobbyists who maintain and ride their Team Losi Promoto-MX regularly, the JAZRIDER JR-LMX08-RD red aluminium tension adjuster offers a simple way to keep chain play consistent and reduce drivetrain wear.
The aluminium construction keeps weight down while resisting routine impacts. These adjusters provide a repeatable axle reference point so you can restore correct tension quickly after service or wheel removal.
Fit the adjusters with standard spanners or hex drivers. Check axle alignment, set the recommended chain slack, then torque the axle hardware to the bike manual. Regular checks after initial runs are recommended.
