Line Comp 30 is a durable alloy mountain wheel built on wider rims for better tyre support. With more support, you can run lower tyre pressure for better traction, more control and a smoother ride. This trail-tough wheel stands up to hard hits, has a proven Tubeless Ready (TLR) design, and includes a 108-tooth Bontrager Rapid Drive hub for quick engagement, fast acceleration and long-lasting performance.
