New fork upgrades.
Advantages of sponge ring.
1. Oil storage performance, so that the inner tube in the process of movement can continue to get lubrication
2. Oil absorption function, can absorb the excess grease on the surface of the inner tube, so that the surface of the inner tube remains clean and fresh

Teflon bearing sleeve, excellent self-lubrication function, effectively reduce the inner tube friction, zero resistance, high lubrication, low noise

The difference between shoulder control and wire control: the shoulder control is the controlled rotation on the fork shoulder of the front fork, and the wire control is that the locking knob on the fork shoulder is changed to a wire control device, which can be installed on the handlebar, so that the locking and Unlocking is easier and faster.

The advantage of the shoulder control is that it is lighter and more agile, because it saves the weight of the wire control and the cumbersomeness of the wire control. The advantage of the wire control is that it is convenient and quick. Handlebars will do the trick, especially in intense riding competitions
