Description
It is an adapter that converts 1050 bearings of YD-2 knuckle to 850 bearings. By using an adapter, we have achieved a weight reduction of over 2g on both sides. Also, as a merit of reducing the bearing diameter,
It excels in low inertia (the force that rolls out with a light force) and improves the rolling of front tires that do not have a drive. * The 1050 size has excellent durability. 4 pieces. Made of machined Duracon.
