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 chasing real trail performance: FOX 34 Rhythm fork and Float DPS Performance shock deliver responsive, balanced suspension, Shimano SLX 12-speed drivetrain ensures crisp, reliable shifting, and a Manic dropper post keeps you in 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 REVIEW
“The changes made to the 2026 Polygon Siskiu T8 certainly fall into the ‘upgrade’ category in our minds… it is impressive to see that Polygon was able to accommodate those upgrades while somehow lowering the price. The frame still looks sharp and continues to stand out in its category.” - The Loam Wolf

FOX 34 FLOAT RHYTHM
The latest FOX 34 Float Rhythm features a stiffer, more precise chassis and refined internals, giving you the confidence to push harder on every trail. Its plush 140 mm FLOAT EVOL air spring delivers improved small-bump sensitivity, while the proven GRIP damper keeps control buttery-smooth from flowy singletrack to chunky rock gardens.

FOX FLOAT DPS PERFORMANCE
This shock combines a larger-volume EVOL air spring with refined dual-piston damping for smoother small-bump feel, better support, and consistent control. A new main piston, valving, and Internal Floating Piston boost performance and tuneability, while the one-piece EVOL sleeve and bottom-out bumper improve responsiveness and add end-stroke progressivity for confident finishes.

SHIMANO SLX/DEORE & BR-MT420
Reliable and precise, Shimano SLX/Deore 1×12 drivetrain features a wide-range 10–51T MicroSpline cassette with Hyperglide+ technology, delivering smooth shifting up or down the cassette even under heavy pedalling load. Powerful BR-MT420 4-piston brakes provide impressive stopping power, excellent modulation, and proven reliability.

IMPROVED WHEELS & MAXXIS
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
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.
