STP 24

£999

Made to help young riders have fun and show off their skills, this mini dirt shredder features a purpose-built aluminum frame and 100mm suspension fork with 24-inch wheels. Trail-worthy MTB components including hydraulic brakes and a dropper seatpost add to its capabilities, giving kids what they need to follow their dirt dreams.

Key Performance Factors

FIT FOR YOUTH

The frame’s low stand-over height offers greater balance and stability with a lower center of gravity that make this model ideal for riders 125-145cm tall. The 24-inch wheels, shorter cranks, and sized-down cockpit components make for smooth pedaling and easier handling, while a dropper seatpost makes it easy to adjust riding position on the fly.

GREATER CONTROL

Youth-specific features including a Crest TR Comp Lite 100mm suspension fork, Grit Core Lite saddle, smaller diameter handlebars, and hydraulic brakes with lighter modulation give STP 24 a smooth, controlled ride, helping young riders focus on building skills and gaining confidence.

PLAYFUL AGILITY

With a lightweight, durable ALUXX aluminum frame, the STP 24 is easy for young riders to maneuver. A shorter wheelbase and chainstays add a playful feel and make it easier to lift the front wheel while riding.

  • Weight
    The most accurate way to determine any bike’s weight is to have your local dealer weigh it for you. Many brands strive to list the lowest possible weight, but in reality weight can vary based on size, finish, hardware and accessories. All our bikes are designed for best-in-class weight and ride quality.
