Release the Beast

The Polygon Collosus N9 is a high-performance enduro bike engineered for riders who demand maximum control, stability, and capability on aggressive terrain. Its ALX Enduro frame delivers 170mm of rear travel optimized for steep descents, enduro racing, and bike-park lines. With progressive geometry and a stiff aluminum chassis, the N9 provides confident handling and superb traction while maintaining strong pedaling efficiency for demanding climbs and technical transitions.

A FOX 38 Float Performance fork with 170mm travel pairs with a FOX Float X2 rear shock to deliver outstanding suspension sensitivity, mid-stroke support, and big-hit absorption. The Shimano XT 1x12 drivetrain offers crisp and reliable shifting with a wide 10–51T cassette, supported by an E13 TRS Plus chain guide with bashguard for rugged protection. Shimano XT M8120 four-piston brakes provide powerful stopping control on long, steep descents. The tubeless-ready Polygon MT6 wheels paired with Maxxis Assegai 2.5" tyres deliver exceptional grip, stability, and cornering performance on rough enduro terrain.

Equipped with a TranzX dropper post, Race Face Aeffect R cockpit, and premium aluminium components, the Collosus N9 is designed for confidence and durability on the toughest trails. Whether charging through enduro stages, tackling rock gardens, or riding high-speed descents, it offers the capability and precision needed for advanced all-mountain and enduro riding.
