REFINED FOR MORE
The revamped Siskiu T adds UDH compatibility, a reinforced rear triangle, and improved internal cable routing for a sleek, future-proof build. A discreet top-tube mount adds utility, while progressive suspension with a larger volume spacer smooths big hits. A 0.5° slacker head tube, slightly steeper seat tube, and longer reach improve stability and climbing balance without changing the familiar Siskiu ride feel.

ULTIMATE VALUE
Built for riders stepping up to full-suspension performance: RockShox Recon Silver RL fork and X-Fusion O2 Pro R shock balance control and comfort, Shimano CUES 1×10 drivetrain keeps shifting simple and reliable, and a Manic dropper post adds trail confidence. Shimano hydraulic brakes and Maxxis Dissector EXO+ tires complete a performance-focused build.

ANY TRAIL, ANY RIDER
The Siskiu T is Polygon's do-it-all trail bike for riders of all levels. From flowy singletrack to technical features, this bike is designed to conquer any trail you encounter. With a lightweight alloy frame, 135mm of rear travel, and 29er wheels, it's both nimble and stable, providing a comfortable and confidence-inspiring ride.
