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!
