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

Performance bead-lock for CR-01 platforms

This precision bead-lock ring is specified for Tamiya CR-01 wheel assemblies as part CR01-04/SI. It secures the tyre bead to the wheel flange to ensure consistent seating across repeated builds and test runs.

The component interfaces cleanly with the CR-01 wheel mounting points and functions as a rigid clamp for the tyre bead. Installation replaces the wheel's outer ring and uses the original fasteners, preserving hub offset and geometry for accurate setup comparisons.

In a tuning or competitive context the ring reduces micro-slip between tyre and rim, improving repeatability when evaluating tyre compounds, inserts or suspension changes. Its role is to remove a variable from control runs so lap-to-lap and run-to-run data remain meaningful.
