Overview
Tekno RC 15x21x4mm ball bearings are genuine replacement bearings sold in a pack of four. They are used in the inner axle position with Tekno RC .4 CVA driveshafts.
Bearings carry every spinning part of the drivetrain and suspension, and worn or gritty bearings rob speed, add heat and wear out the parts around them. Replacing them with the correct size keeps everything turning freely.
