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.
