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 ready to push their limits: RockShox Recon Silver RL fork and Deluxe Select+ shock deliver composed suspension performance, Shimano Deore 12-speed drivetrain ensures crisp, reliable shifting, and a Manic dropper post adds confident control. Shimano 4-piston brakes and Maxxis Dissector EXO+ tyres 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.
INDUSTRY REVIEWS
"When it comes to bang for buck, the Siskiu T7 29 has to be one of the most impressive bikes out there" - bikeradar
ROCKSHOX RECON SILVER RL FORK
The Recon Silver RL offers 140 mm of smooth, responsive travel via its Solo Air spring, with Motion Control™️ damping for rebound and low-speed compression to lockout. Boost 15x110 mm spacing, Fast Black 32 mm steel uppers, and a cast brace deliver stiffness, precision, and clearance for up to 2.8" tyres.
ROCKSHOX DELUXE SELECT+
The all-new Deluxe Select+ pairs a DebonAir+ spring and larger-volume spacer for a progressive, supportive feel, while the new castled bottom out bumper reduces harshness from hard hits. Rebound and two-position compression adjustments keep descents plush and climbs efficient - all in a lightweight package.
SHIMANO DRIVETRAIN & BRAKES
Reliable and precise, Shimano Deore 1×12 drivetrain features a wide-range 10–51T MicroSpline cassette with Hyperglide+ technology, which allows seamless shifting up or down the cassette even under heavy pedalling load. Powerful BR-MT420 4-piston brakes deliver impressive stopping power, excellent modulation, and proven reliability.
IMPROVED WHEELS + TYRES
Over 200 g lighter, this reengineered wheelset features a reinforced nipple channel and offset spoke lacing for balanced tension, paired with upgraded Sapim stainless spokes. A hookless rim bead shrugs off impact damage, while a destressed, hand-retention build helps the wheels stay true ride after ride. Paired with grippy Maxxis Dissector tyres, it delivers speed, strength, and confident handling when trails get technical.
X‑FUSION MANIC DROPPER POST
Confidence on every descent is just a lever-press away. The internally routed Manic LC dropper offers smooth travel that can be stopped at any position within its set range, letting you quickly get the saddle out of the way. Paired with a new composite lever for lighter, stiffer actuation, its low stack height and micro-adjust clamp maximise fit, keeping you in control.
