Polygon Siskiu T8 Mountain Bike 27.5" Black 17"

The Siskiu T is built around a new lightweight, hydroformed 6061 aluminium Boost frame and longer 140mm (29er) / 150mm (27.5") travel. By utilising a one-piece linkage system, Polygon has been able to keep the frame weight down 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 with a lot more control when exiting high-speed corners and negotiating rock gardens. The Boost design means that Polygon has been able to include 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.
