enhancing overall riding experience.

TUNING WITHOUT COMPROMISE

LSC (Low Speed Compression)
Superior pressure balance and frequency response providing the ultimate overall responsiveness and performance for riders.

Optional DSC note: We’re fine tuning the DSC now and it will be available in a couple months (likely early 2025). The DSC will offer a wider adjustment range than the LSC. LSC and DSC fit in the same cavity and are cross compatible (with a rebuild). Both will be offered as service parts. (ie. if you purchase the current LSC now, it can be serviced and tuned to add DSC later. More details to follow)
