Tamiya CR-01 Bead-lock Ring CR01-04/SI by 3Racing  [CR01-04/SI]

Secure bead-lock for CR-01 wheels

This is an RC-scale bead-lock ring made for Tamiya CR-01 wheel assemblies, listed as part CR01-04/SI. The component is designed to retain the tyre bead and preserve consistent seating during regular running and setup changes.

The ring matches the CR-01 wheel interface and acts as a mechanical clamp that locks the tyre bead against the wheel flange. Fitment replaces the wheel's outer ring and uses the existing wheel screws for reassembly, so hub geometry remains unchanged.

From a setup point of view this part helps keep tyre alignment and reduces small slips between tyre and rim during low-speed technical driving or trail crawling. Fit it when you need repeatable tyre positioning after tyre swaps or when comparing compounds and inserts.
