The Specialized Riprock 24 is the bike that turns every ride into an adventure.
Designed for young riders who want to explore the off-road world with safety and fun, it offers modern technology, total comfort, and true mountain bike performance.
Thanks to progressive geometry, hydraulic disc brakes, Ground Control tires, and wide-range drivetrain, the Riprock 24 is designed to tackle every climb and descent with confidence and control.
It is lightweight, sturdy, and proportioned for kids, to ensure balance and safety with every pedal stroke.
Designed for Children's Confidence and Comfort
Because for kids to pedal with confidence, they need to feel comfortable.
Specialized has rethought every detail of the Riprock 24, based on biomechanical data specific to younger riders:
130 mm Bridge Kids saddle, shorter and more comfortable.
Reduced Q factor and short cranks, for better alignment of hips, knees, and ankles.
Narrower grips and new frame geometry, for natural and secure handlebar control.
An ergonomic design that reduces fatigue, prevents injuries, and promotes a smooth and stable pedal stroke.
Modern Performance in a Junior Size
The Specialized Riprock 24 inherits the DNA of adult MTBs:
A1 Premium alloy frame with internal cable routing for a clean look and extra protection.
1x9 microSHIFT Advent drivetrain with wide range (11-42 teeth) to easily tackle climbs and descents.
Promax DSK-926 hydraulic disc brakes for safe and modulated stopping power.
Sleek geometry and open head tube, for exceptional stability on trails.
Every component is optimized to offer lightness, precision, and fun on every ride.
Light, Agile, and Ready for Every Trail
The new aluminum frame A1 Premium Butted Alloy is sturdy and lightweight, ideal for young riders looking to improve their skills.
The alloy fork and Ground Control 24x2.1 tires ensure secure grip on any terrain, while the smooth drivetrain and ergonomic handlebar guarantee control and comfort.
Perfect for forest rides, trail routes, and dirt adventures.

A Complete Guide to Bike Sizes
Foreword: Not all bike sizes are the same
Each type of bike has a specific frame and often uses a different size scale. For example, a road bike with a 54cm frame might be considered a medium size by one brand, but a large by another.
Bicycle adjustment margins
Some types of bikes, like gravel bikes, offer a wide range of adjustments, adapting to different body types. Other models, however, have limitations in this regard. This is an important aspect to consider.
