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.

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
The Fox Float DPS Performance Series EVOL LV offers a 2-position lever for quick Open and Lock adjustments. With its EVOL air spring, rebound adjuster, and volume spacers, it delivers enhanced tuning and fine-tuned progression for optimal ride quality.
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.
