Tamiya CR-01 Outer Bead Clamp CR01-04/SI by 3Racing  [CR01-04/SI]

Outer bead clamp for CR-01 rims

This bead-lock ring is produced for use with Tamiya CR-01 wheels and carries the part reference CR01-04/SI. It is intended to lock the tyre bead in place so seating remains consistent through multiple runs and setup changes.

The clamp interfaces with the CR-01 wheel and secures the tyre bead to the rim flange. Installation replaces the wheel's outer ring and is fastened using the original wheel screws, allowing rebuilds without affecting hub alignment.

For tuning it improves repeatability of tyre position and cuts down incremental slip between tyre and rim when driving slowly over technical sections. Use it when swapping tyres or evaluating different compounds and inserts.
