Polygon Siskiu T6 - Mountain Bike MY26
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+ 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
“You'd easily think you were riding a bike worth a lot more.” - AMB MAG
ROCKSHOX RECON SILVER RL FORK
The Recon Silver RL delivers RockShox’s proven trail performance in a versatile 140mm package. Its Solo Air spring gives a smooth, responsive feel, while external rebound and compression adjusters let you fine-tune the ride. Boost 15x110 mm spacing and a Maxle Stealth axle add stiffness and precise steering for confident handling on varied trails. Durable and easy to maintain for regular trail use.
X‑FUSION O2 PRO R REAR SHOCK
Compact, lightweight, and tuned for trail riding, the O2 Pro R delivers consistent damping and excellent control. With adjustable rebound, this metric shock keeps the rear end supple on climbs and efficient when pedalling, while soaking up rough descents with a plush, predictable feel. Its air-sprung design allows easy tuning to match different rider weights and styles.
SHIMANO DRIVETRAIN & BRAKES
The Shimano CUES U6000GS 1x10 drivetrain simplifies riding with a narrow-wide chainring and intuitive shifting. Its clutched rear derailleur secure the chain over rough terrain, reducing slap and drops. A wide-range 11-48T cassette handles steep climbs and fast descents, while Shimano MT200 hydraulic disc brakes deliver consistent, well-modulated stopping power in most weather and trail conditions.
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.
