Polygon Siskiu T series is built around a new lightweight, hydroformed 6061 aluminium Boost frame and longer 140mm (29er) / 150mm (27.5″) travel.

All models of Siskiu T are built by utilising a one piece linkage system, the frame weight is kept to a minimum whilst reinforcing high-stress areas and reducing flex under heavy loads. The rear swing triangle also features a unibody pivot bridge that stiffens the rear wheel and provides you a lot more control when exiting high-speed corners and negotiating rock gardens. The Boost design means that the Siskiu T now comes with wide 29mm rims with 2.6″ tyres (27.5″ wheel) and 2.35″ tyres (29″ wheel). The frame is finished off with a tapered headset, rear thru axle, and internal routing for gears, brakes and 150mm dropper post. If you’re looking for a bike to do it all with killer style and a dependable, high quality, trail ready components list, then the Siskiu T8 is the bike for you.
