Product details
Add the Progressive Suspension fork preload adjuster to stiffen up the front fork for aggressive riding in the canyons, or decrease the preload to soften the suspension for a day of comfortable cruising. The ability to change preload settings also provides improved front suspension performance when going from a single rider to a rider with passenger configuration.
