High-quality, high-performance replacement fork springs. A Progressive Suspension rate spring has the advantage of a rising rate resistance to compression. The benefit is the spring can be soft enough at the start of the travel to offer a “plush” ride, yet firm enough at the end of the travel to soak up the big bumps. Spring rates have been chosen to reduce front-end dive during braking, yet still provide excellent ride comfort. Made in the U.S.A.
