Mountain Bike Frames

If you love tight and twisty single-track, bombing down a hill at maximum speed, or just looking for a fun winter project, then check out the frames below. Mountain bike frames are perfect for building up a custom bike from scratch or replacing your damaged or old MTB frame with something better. They come in a variety of frame materials, like carbon fiber, aluminum, steel or titanium, and a range of tube shapes, head tubes and bottom bracket shells. The right mountain bicycle frame, with the right geometry, can make difference between enjoying a ride and just tolerating it. Shop our full selection here.
