Technical Specifications
Kid-sized for shredding singletrack, the Hotrock 24 XC Disc comes equipped with everything your little ripper needs to start riding with the big kids, including hydraulic disc brakes. It features a lightweight, yet durable, A1 Premium Aluminum frame that's designed to take a hit while they find their legs on the pump track, while chatter and bumps are handled by the coil-sprung SR Suntour fork's 63mm of travel. Then there are a whole host of other components that are plenty tough enough to stand up to your little one, so you can rest assured that you'll be spending more time riding with your kid then waiting in line at the repair counter.
  • Tough, light, and durable, the A1 Premium Aluminum frame is built to stand up to years of tough riding.
  • SR Suntour suspension fork offers 63mm of coil-sprung travel that smooths out bumpy, rough terrain
