Your Blank Canvas for Dirt Jump Progression

The 2026 Giant STP 26 Frame in Shadow Mist gives riders the perfect foundation for building their ultimate dirt jump or pump track machine. With a lightweight yet incredibly strong ALUXX aluminium construction and horizontal sliding dropouts for single-speed setups, this frame is designed for riders who want full control over their dream bike build.

Purpose-Built for Hard Riding

Constructed from Giant’s proven ALUXX-grade aluminium, the STP 26 frame delivers the toughness dirt jump riders demand while still being light enough for fast pop, responsive handling and smooth whips. Its 135x10mm horizontal sliding dropouts allow perfect chain tensioning for single-speed builds, giving you simplicity, strength and reliability for dirt sessions, park laps and street riding.

Dialled Geometry for Jumps and Pump Tracks

The STP 26’s geometry is engineered for agility, stability and maximum airtime control. A low stand-over height keeps the centre of gravity balanced, while the short chainstays and compact wheelbase offer fast handling and flickability — ideal for boosting jumps, railing berms and trying new trick lines with confidence.

Build It Your Way

Whether you’re aiming for a clean single-speed DJ setup, a street build with rugged components, or a lightweight 26-inch trail playbike, this frame gives you unlimited customisation options. Pair it with a DJ-specific fork, wide rims, and your choice of cockpit components to create a ride that feels uniquely yours.

Who’s It For?

The 2026 Giant STP 26 Frame in Shadow Mist is ideal for riders who want to create a personalised dirt jump bike from the ground up. If you’re building a custom pump track, jump park or street machine, this frame offers the strength, geometry and reliability needed to progress your skills.
