Polygon Siskiu T Series Mountain Bikes
The Polygon SISKIU T-Series is the definitive modern trail bike and the number one choice for riders looking for high-end performance without the big price tag.
Built around a stiff, responsive alloy frame, 29er wheels and a proven 1x drivetrain, the SISKIU T balances technical climbing efficiency with aggressive descending stability.
Updated from the previous version, the 64.5° head angle provides stability on steep descents, and the 77° seat tube angle puts you in an efficient, upright pedalling position. 430mm chainstays keep corning snappy, whilst a 39mm bb drop, shorter seat seat tubes and low standover improves handling.
With UDH dropout standard, the SISKIU T is now compatible with all modern shifting systems available on the market.
Cables are now routed internally for an extra clean look, protecting them from the worst of the weather.
Compatible with aftermarket accessories, the top tube mounts make it possible to carry all your spares necessary trailside repair - no backpack needed.
