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.

A TRUSTED BRAND

Polygon is a factory-direct brand with over 30 years of experience crafting high-performance bikes at competitive prices. Vertically integrated manufacturing ensures quality and cost savings. 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

“An entry-level MTB for those looking to improve their skills and have a great time doing so." - BikeRadar

ROCKSHOX SUSPENSION

The Siskiu T7's RockShox Recon Silver RL fork and Deluxe Select+ shock deliver performance unseen at this price point. Easily adjustable with rebound, compression, and lockout, they're fine-tuned for your weight and riding style.

ONE-PIECE LINK

Polygon's proven One Piece Unibody Pivot Bridge delivers a reliable, lightweight, and stiff linkage for an active feel on both climbs and descents. This simple design sheds unnecessary weight while boosting stiffness.

DROPPER POST

The TranzX JD-YSP23JL dropper post lets you effortlessly adjust saddle height with a flick of the lever. Gain confidence and control on descents by lowering your centre of gravity for technical terrain and steep slopes.

SHIMANO DEORE 1X12 DRIVETRAIN

The Shimano Deore drivetrain is paired with an 11-51T cassette, giving you a +500% gear ratio to get up and down the mountain with ease and features Shadow+ technology.

SIZE-SPECIFIC WHEELS

The Siskiu T's Wheel Fit Size System ensures the perfect fit for every rider. Smaller sizes get nimble 27.5" wheels, while larger frames roll on confidence-inspiring 29" wheels. Medium riders have the choice!
