Tamiya 54426 RM-01 Bearing Adapter Set OP-1426  [54426]

Compact Bearing Conversion for RM-01

The Tamiya 54426 adapters permit the use of 850 ball bearings in place of the larger 1150 units on the RM-01 chassis, cutting roughly 3.4 grams from the hub assembly. The reduced rotating weight tends to make steering inputs feel more immediate and can aid lap time consistency.

Compatibility and Fit

These adapters are produced for RM-01 upright locations and accept 850 bearings that are sold separately. They slot into position with minimal fuss and improve wheel rotation smoothness while keeping the original hub geometry intact.
