Double-bearing front axle for use with RD/SD/MD series front axles. The double bearing holding the axle shaft distributes friction and reduces rotational resistance of the front tire to the utmost limit.
Axle shaft is made of steel but ⌀3mm to reduce weight and rotational moment. The front end rolls better during acceleration, increasing acceleration at the exit of corners and preventing spinning. Tread adjustment is also possible by replacing the spacers.
