7075 Aluminium Touring Spur Adaptor for TB-03

This spur adaptor is built for the TB-03 platform and carries part number TB03-14. Machined from 7075 aluminium, it replaces the standard spur adaptor to add rigidity at the spur gear interface and reduce drivetrain looseness.

Fitting is aimed at TB-03 builds that accept the standard adaptor geometry. The unit connects to the existing spur gear interface and preserves original mounting, so installation is about proper seating and checking pinion-to-spur engagement rather than altering fixings.

As a tuning item the aluminium adaptor helps keep mesh stable after repeated use and under higher loads compared with softer parts, making it a sensible upgrade for drivers trimming drivetrain play and improving consistency between setup changes.

Will this fit standard TB-03 spur gears?

Yes, it follows the conventional TB-03 adaptor form. Confirm your spur and casing dimensions match the TB-03 standard before fitting.

Does the adaptor require shims or spacers?

Most TB-03 setups will not need additional shims as the adaptor preserves the original spacing, but always verify pinion mesh and add thin shims if required to get correct engagement.

How does this affect long term maintenance?

The harder alloy reduces deformation under load, so you may see more consistent mesh over time; still inspect threads and bearing seats and replace the adaptor if any wear appears.
