Progressive version of the superb VALT spring.

The performance of your shock is directly related to the quality of your spring. VALT® is a lightweight coil spring that offers a significant weight reduction over standard steel springs. Designed to be as light as possible without sacrificing action or durability, the high quality steel in VALT® allows for less material to be used in the coils. Riders can enjoy the performance benefit and consistency without the weight penalty. The large inner diameter of the VALT® means it will fit Cane Creek shocks and most other shock options on the market.
