Polygon Collosus N7 (Light Green)
8994981064767-2025
A second-generation enduro bike for riders who want race-proven geometry and the flexibility to run full 29er or mullet, built with two seasons of World Cup development behind it.
Overview
The Collosus N7 carries forward the 435mm chainstay length that Polygon's engineers found gave the best balance of maneuverability and stability — but almost everything else has been reworked. A redesigned, stiffer chainstay pairs with new flip-chip dropouts that let you switch between a full 29er setup and a mullet configuration without changing frames, while UDH dropouts open the door to modern T-Type drivetrains.
Power goes through a Shimano Deore 1x12-speed drivetrain with a wide 10-51T cassette, and a RockShox ZEB Base fork with 170mm of travel soaks up the big hits. The shock has moved from trunnion to a 230x65mm metric mount for better tuning, and a redesigned lower link with added material and through-axles eliminates flex for a more responsive ride.
It's built from two full seasons of collaboration with the Polygon Factory Racing team across the EDR World Cup circuit — real race development, not a desk exercise.
Why You'll Like It
Switch wheel sizes without switching frames
New flip-chip dropouts let you run full 29er or a mullet (29er front, 27.5" rear) setup while keeping the geometry intact.
Ready for modern drivetrains
UDH dropouts mean the frame is compatible with T-Type drivetrains for seamless integration with the newest shifting systems, not just what ships in the box.
A stiffer, more responsive rear end
The redesigned lower link adds material and through-axles specifically to eliminate flex, translating to a more direct, confident ride through rough sections.
Better shock tuning
Moving from a trunnion mount to a 230x65mm metric shock improves both suspension performance and tuning range.
Proven where it matters
Two seasons of development with Polygon Factory Racing across the EDR World Cup circuit back up every spec choice on this bike.
Who Is It For?
The Collosus N7 is built for riders who want a genuinely race-capable enduro bike — aggressive descents, technical trail features, and the kind of terrain that punishes a bike not built for it.
In India, that means riders heading to the hill stations and trail networks around Bangalore, Coorg, or the Himalayan foothills where terrain gets genuinely technical — this isn't a bike built for flat city commuting, it's built for the days when the trail gets serious.
It's also a strong choice for a rider moving up from a trail hardtail who wants real enduro capability and the flexibility to experiment with mullet setups as their riding evolves.
Good to Know
The flip-chip dropouts make switching between 29er and mullet configurations straightforward at home — no special tools or shop visit required for the swap itself.
UDH compatibility means this frame is future-proofed for newer drivetrain standards as they become available, not just what it ships with today.
