Ultra Ripster 20in UDING SD32 Air Suspension Fork - 60mm travel

The Gen 1 Ultra Ripster is a compact bike with small wheels, so a fork that softens the road matters more than it might on a big-wheel bike. This UDING SD32 air fork gives you 60mm of travel on 20-inch wheels and lets you tune the feel.

Strong points: an air spring can be adjusted to rider weight by changing pressure, which coil forks in this price class usually cannot do. That means a lighter rider and a heavier rider can both get a fork that moves the way it should.

Compared with a stock rigid fork, this one takes the sting out of cracks and speed bumps. Compared with a generic 20-inch fork, it is chosen for the Gen 1 Ultra Ripster, so fit is not a guessing game.
