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.
