Origin

Polygon launched the Collosus family in 2020 as a rebrand and upgrade of the Siskiu N enduro lineage, adding a trail-focused Collosus T alongside the enduro Collosus N. The 2022 Collosus generation introduced UDH dropouts (compatible with SRAM's T-Type Eagle AXS system) before SRAM's own bikes shipped with UDH — a rare instance of a value brand ahead of the component curve. The Collosus TLE brought a full-carbon frame to the lineup.

Specifications

Brakes: Shimano XT M8120 4-piston hydraulic disc, 203mm front / 180mm rear rotors
Wheels: Entity XL3 tubeless-ready 29-inch; 15×110mm / 12×148mm Boost

The verdict

+Strengths

UDH dropout adds SRAM T-Type compatibility that extends the platform's long-term upgrade path
FOX 38 + Float X2 suspension on N-series is top-shelf damping at below-average pricing
Collosus N geometry (170mm, 435mm CS, slack HTA) is race-capable for enduro

−Weaknesses

ALX alloy frame is heavier than carbon enduro alternatives from competing brands
Service network outside of Asia and Australia remains thin
Collosus T competes in a crowded 140mm trail segment where differentiation is harder
