Description

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, 135/140mm of rear travel, and size-specific wheel sizes, it's both nimble and stable, providing a comfortable and confidence-inspiring ride.

ULTIMATE VALUE

Don't let the price fool you - the Siskiu T delivers high-performance features typically found on more expensive bikes. Modern geometry, quality air suspension, a 1x drivetrain, and a dropper post give you the tools to climb with ease and attack the descents. Experience the thrill of modern trail riding without breaking the bank.

Their mountain bikes have been tested on the world stage at events like Redbull Rampage and the World Cup circuit, boasting a 5-year frame warranty for peace of mind.

INDUSTRY REVIEWS

The new Polygon Siskiu T9 has impressed not just because of its incredible value for money, but also due to its ride quality on the trail. - Flow Mountain Bike

FOX 36 PERFORMANCE ELITE

Stiffer, lighter, and more tunable than ever, the FOX 36 performance elite is in a class of its own. The 36 offers the highest stiffness-to-weight ratio in its class, GRIP 2 damper and EVOL spring.

FOX FLOAT X PERFORMANCE

A lightweight chassis, EVOL air spring, and dual piston damper with a 3-position switch create a pedal-friendly shock that soaks up the bumps.

SHIMANO XT 1X12 DRIVETRAIN

The Shimano XT drivetrain is paired with a 10-51T cassette, giving you a +500% gear ratio to get up and down the mountain with ease.

TRP DHR EVO BRAKES

The World Cup-proven 4-piston brake calipers of the DH-R Evo have been paired with 180mm rotors and feature adjustable lever reach.

ONE-PIECE LINK

The proven One Piece Unibody Pivot Bridge removes the bells and whistles - leaving you with a reliable and uncomplicated linkage that gives you an active feel on the bike, while reducing the frame's weight and increasing the stiffness.

A beast of a bike

The Polygon Siskiu T9 29″ combines a stout 6000‑series alloy frame and proven single‑pivot linkage with a Fox 36 Performance Elite fork and Fox Float X shock delivering 140 mm front and 135 mm rear travel. Rolling on grippy Maxxis Assegai TR EXO 29×2.6" tires laced to robust Entity rims, it’s driven by a crisp‑shifting Shimano Deore XT 1×12 drivetrain (10–51 T) and hauled down by TRP four‑piston brakes. A smooth‑actuating dropper post and thoughtfully tuned geometry round out a package that feels both confident and versatile on a variety of terrain. On the climbs, suspension bob is minimal, and the wide‑range cassette keeps you spinning easily up steeps. Heading downhill, the T9’s chassis stays planted through rock gardens and rolls over obstacles with composure, yet remains agile enough to dart through tight, techy sections. If you’re after a high‑performance 29″ trail bike that undercuts many carbon‑frame rivals, the Siskiu T9 is a standout choice.

Price for performance

The D7 delivers blistering speed and confidence on every trail. Assembly was a breeze—the bike arrived 95% pre-built with all the tools and parts I needed to roll out in minutes. Once dialed in, its plush suspension soaked up chatter and rock gardens with effortless grace, while the crisp, lightning-fast shifting kept me in the perfect gear through every climb and descent. From my first ride, it felt intuitive and responsive, easily customized to my preferences. If you’re an XC rider hunting for a high-performance full‑suspension rig, the D7 should be at the top of your list.
