Versatile Trail Muscle

Why We Love It
The Polygon Siskiu T 27.5 is for the rider who wants a bike that possesses the capability to ride a broad range of trails. With 140mm of rear travel and 150mm up front blended with a progressive geometry that keeps you feeling in the driver seat.
Polygon's aluminum Siskiu frame is dependable, impressively lightweight and keeps the cost low (meaning more post ride tacos?). It's hard to beat the versatility for the dollar that Polygon delivers.
  • 27.5" wheels are nimble and quick to respond
  • 140/150mm rear/front travel gives this bike plenty of versatile muscle
  • Progressive geometry keeps you confident in the driver seat no matter what the terrain delivers
Master Mechanic’s Notes
  • Light scratches on the brake levers, fork lowers, crank arms, seatstays, chainstays, & rims
  • Moderate scratches on the top tube
