Product Description
The SR Suntour XCM34 is a durable 27.5-inch mountain bike suspension fork designed for dependable trail performance, recreational riding, and rugged commuting. Its medium coil spring and 120mm of travel provide consistent support and control over rough terrain, while the sturdy 34mm chassis helps improve front-end stability.
This fork features a 15x110mm Boost thru-axle interface, external rebound adjustment, and mechanical remote compression control. Fender mounts add versatility for commuting and all-weather use.
