Description

ENDURO BEAST

The new Collosus N blends race-proven performance with enduro-ready versatility. Developed with input from the EDR World Cup and Polygon Factory Racing, it’s built to tackle everything - gnarly trails, big hits, and steep climbs. With 170mm of suspension and 29" wheels, it’s the perfect bike for riders who demand it all.

REFINED FOR MORE

The updated frame now has UDH compatibility, longer chainstays for improved stability, a stiffer rear end with adjustable bolt-on dropouts to handle mixed wheel sizes. A reengineered lower link to fine tune the flex to where it needs to be, while the new metric shock allows for more shock options and better stability through the system for increased performance. Plus, a beefier 34.9mm dropper post for enhanced durability and customisation.

IFS LINKAGE DESIGN

Independent Floating Suspension (IFS) system provides unparalleled control and responsiveness. By independently controlling wheel path, anti-squat, and leverage curve, the IFS system delivers both plush small-bump sensitivity, efficient pedaling, and progressive bottom-out resistance.

FOX 38 FLOAT PERFORMANCE

Engineered for aggressive enduro riding, the FOX 38 FLOAT Performance delivers stiff, confident front-end support. With its GRIP damper and beefy 38mm stanchions, it stays planted through chunky rock gardens and steep chutes—keeping the ride smooth, precise, and in control at speed.

FOX FLOAT X2 REAR SHOCK

The Float X2 is built for high-speed hits and big terrain. Combining the plushness of a coil with the lightweight efficiency of an air spring, it delivers incredible damping and endless tunability—giving riders a dialed-in feel no matter how rough or fast the trail gets.

SHIMANO XT 4-PISTON BRAKES

Confident braking starts here. The Shimano XT 4-piston calipers deliver strong, consistent power with refined modulation—perfect for technical descents and fast-paced enduro lines where control is everything.

RACE FACE AEFFECT 35 COCKPIT

Designed for durability and precision, the Race Face Aeffect 35 handlebar offers a stiff, responsive platform for aggressive riding. Its 35mm diameter boosts strength and control on rugged trails, giving riders the confidence to charge harder through demanding terrain.

MAXXIS ASSEGAI TIRES

An aggressive, grippy, and incredibly predictable tire that thrives on everything from loose dust to slick roots. Its standout feature is the edge-to-edge control—those small knobs between the center and side lugs deliver smooth, consistent grip through corners, giving you confidence when things get rowdy.
