Progressive Front Fork Springs Rate: 45 lbs/in-65 lbs/in (11-1578)
- 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
- Sold in pairs
- Made in the U.S.A.
