COLLOSUS N: Enduro, Evolved. Built for Racing, Refined for Riding
Enduro | 170mm Travel | ACX Carbon & ALX Alloy | 29" Wheels
The Polygon COLLOSUS N is our ultimate enduro mountain bike. Developed over two seasons by the PFR team on the EDR circuit, we've refined every detail and link to ensure this long-travel MTB climbs efficiently and descends with total authority.
At the heart of the COLLOSUS N is our Independent Floating Suspension (IFS) 6-bar platform, designed to separate braking forces from suspension movement. Combined with a metric shock and modern geometry, our flip-chip dropouts allow you to switch seamlessly between the raw speed of a full 29er or the flickable handling of a mullet setup.

ENDURO ?
For us, Enduro bikes should be burlier to nail larger drops more efficiently and literally anything that the rugged mountain throws. And, yeah! We're here for all of that. We've packed all that we know these years to build you an Enduro bike that is faster on the descents and also for pedalling back uphill to start another one. Get ready to feel the rage of mountains and be in a class of your own. See more...
