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.

ULTIMATE VALUE

INDUSTRY REVIEWS

"The bike is a solid value, looks so good and is more than capable to be ridden at a very high level.” - Loam Wolf

FOX 34 RHYTHM FORK

Experience 150/140mm of air-sprung travel for a smooth and controlled ride. Its Grip damper and adjustable rebound provide a responsive feel on the trail. Add or remove volume spacers to fine-tune bottom-out resistance.

FOX FLOAT DPS SHOCK

Featuring three compression settings for quick adjustments on the fly. Its EVOL air spring and rebound adjuster offer further tune-ability, while volume spacers allow you to fine-tune the progression.

ONE-PIECE LINK

Sometimes simple is better! The linkage-actuated single pivot offers active and progressive suspension making for a supple ride on technical sections and a playful ride on flow trails, while the one-piece pivot bridge reduces flex and saves weight.

SHIMANO SLX 1X12 DRIVETRAIN

The 12-speed drivetrain is paired with a Sunrace 11-51T cassette, giving you a +500% gear ratio and features Shadow+ technology.

WHEELSIZE FIT

The perfect fit for all riders. Smaller sizes come in 27.5" for nimble handling and a lower standover. Medium riders can choose between 27.5" or 29" wheels, while larger sizes get the added stability and rollover of 29" wheels.

Assembly

Your bike needs minor assembly before riding; use the tools and videos included.

As a guide, it'll take 10-40min depending on whether you're an experienced bike assembler or have little to no mechanical experience.

Side Note: Your cables will stretch during the initial bed-in period and must be adjusted by an experienced mechanic around 150km of riding.
