Mach 4 SL Factory Frame

What Our Gearhead® Experts Are Saying:

"The Mach 4 SL is the kind of frame that makes you rethink what an cross-country bike can do. It’s impressively light, but it doesn’t feel twitchy or unstable like some weight-focused race bikes. The DW-Link suspension is incredibly efficient, smoothing out chatter without robbing power. Plus, the flip chip travel adjust means I can tweak the setup depending on the terrain. Whether I’m sprinting for a KOM or logging big miles, this frame is built to perform."
