Dirt skills start here. With a lightweight aluminum frame that has a low stand-over height and 20-inch wheels, the new STP 20 gives kids the confidence and maneuverability they need to start leaning into the turns, shifting their weight, and popping some air. It’s all the things that make riding fun.

FIT FOR YOUTH

The frame’s low stand-over height offers greater balance and stability with a lower center of gravity that’s ideal for riders 110-130cm tall. The 20-inch wheels and shorter 105mm cranks make for easier handling and smoother pedaling.

GREATER CONTROL

Youth-specific components including a Grit Core Lite saddle, smaller diameter handlebars, and hydraulic brakes with lighter modulation give STP 20 a smooth, controlled ride, helping young riders focus on building skills and gaining confidence.

PLAYFUL AGILITY

With a lightweight, durable ALUXX aluminum frame and Advanced-grade composite fork, the STP 20 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.
