Description
The STP 20 is a lightweight, confidence-building bike for riders discovering off-road fun. Its stable geometry, low stand-over height, and youth-specific components make it ideal for developing skills on pump tracks, dirt jumps, or local trails. BUILT TO LAST: The ALUXX-grade aluminum frame combines durability and low weight, giving young riders a solid platform to ride, learn, and progress. The STP 20 FS adds a 63 mm suspension fork for extra comfort and control on rougher terrain. YOUTH-TUNED CONTROL: Designed for riders 110–130 cm tall, the STP 20 features youth-specific components, including 105 mm short cranks, a Liv Grit Core Lite saddle, and smaller-diameter handlebars for an optimal fit. Youth-tuned hydraulic disc brakes provide smooth, predictable stopping power, while the low bottom bracket height ensures a stable, balanced feel on all terrain. TRICK-READY HANDLING: The 20-inch TRA 2 WheelSystem with Wide Guard rim technology provides durability and traction for playful, confident riding. Front and rear thru-axles add steering precision and stability, while the short rear center keeps handling nimble and easy to maneuver.
