Overview

Geometry
Whether you've been riding trails for decades or you're just starting to cut your teeth, the Rockhopper Comp 29 will take your rides to the next level. We built it with just the right balance between performance and durability, and not to toot our own horn, but we nailed it. The Comp 29 features corrosion-resistant hardware for long wear, our Trail 29 Geometry that provides confident handling and efficiency, and an alloy frame construction that's equal parts light and compliant.
  • The frame is constructed from lightweight A1 SL aluminum in order to provide a compliant, durable platform to support our acclaimed Trail 29 Geometry. Combined, you get a bike that's more than efficient on climbs and eager to get down to business on descents.
  • SR Suntour XCR-Air fork features 80/100mm (size-specific) of suspension travel that swings well above its weight class.
  • Shimano Deore rear derailleur provides crisp, reliable shifting that you can count on when the going gets rough. With it, you'll be able to precisely move through the wide, 11-36t gear range to make cruising the flats almost as easy climbing those hills.
