Highlights
- Lightweight Alloy Frame – A1 Premium Butted Alloy with internal cable routing provides durability while keeping the bike light and manageable for young riders.
- Kid-Specific Cockpit – Shorter 115mm crank arms, narrow Q-factor, and junior-sized touchpoints improve comfort, efficiency, and control.
- Modern Trail Geometry – A slack head tube angle and balanced wheelbase give young riders confidence and stability on descents and technical terrain.
Description
Freedom is the absence of fear. And fearlessly riding requires a bike that can handle your kid’s imagination. It’s why Specialized designed the Riprock to be a mountain bike inclusive of all the features needed for superior ripping—like modern geometry, Ground Control tires, hydraulic disc brakes, and internally routed cables. Finally, they threw in a wider-range drivetrain, making Riprock the perfect bike to inspire young riders to climb higher and tackle the downhills freely.
Kids can’t confidently ride if they’re not riding comfortably. With Riprock, fit comes first. They used data to reimagine everything from how they grip to how they sit to create a bike specifically and proportionally for kids. They did all this because comfort creates confidence. And more confidence always leads to more fearless riding.
