Polygon Collosus N8: Release the Beast
The next generation of our flagship enduro machine is here. Ride faster, track better, and leave the competition in the dust with the completely redesigned Polygon Collosus N8. Shaped by feedback from our pro athletes and proven on the world stage with Polygon Factory Racing at the Enduro World Series, this bike is the ultimate tool for riders chasing podiums.
Pro-Proven Carbon Performance
The heart of the new Collosus N is its advanced carbon front triangle, which drops a significant 500g without sacrificing strength. This isn't just about saving weight; it delivers a massive boost in control and damping, giving you a more confident and comfortable ride on the most demanding terrain. Paired with a robust alloy rear triangle, the N8 offers the perfect blend of razor-sharp handling, durability, and smart value.
Your Bike, Your Rules: Unmatched Adjustability
The 2025 Collosus N is engineered for versatility. A new flip-chip system allows you to effortlessly switch between a full 29er setup for all-out speed and an MX (mullet) configuration for playful agility, all while maintaining consistent geometry. Furthermore, a tapered headtube opens the door for angle- and reach-adjust headsets, giving you the power to fine-tune your ride for any track or style.
Stow & Go with the "POLYPOCKET"
Dialed for Descent
At its core, our proven Independent Floating Suspension (IFS) system delivers efficient pedaling on the climbs and precise handling through high-speed hits. We've equipped the N8 with a top-tier FOX 38 Performance fork and a FOX Float X2 rear shock, giving you 170mm of trail-devouring travel. Paired with a reliable SRAM GX Eagle 12-speed drivetrain and powerful Magura MT7 brakes, the Colossus N8 is a complete, race-ready package straight out of the box.
