Description
Fork Preload Adjuster – 39 mm
Upgrade your front suspension control with these Speed Merchant 39 mm Fork Preload Adjusters — a precision-machined solution that lets you fine-tune preload without cracking open your forks or trimming spacers. With nearly a full inch of adjustment, these caps make dialing in your front end fast, accurate, and repeatable. Whether you're stiffening things for aggressive riding or softening the feel for comfort, these adjusters give you the flexibility your fork tubes should’ve had from the factory. Made in the USA and built for riders who want more control out of their 39 mm front ends.
