Summary

The Polygon Collosus is a mixed bag in the enduro category, praised for its modern geometry, efficient pedaling, and value for money, but criticized for its weight and some setup challenges. Its suspension performance is noted for being active and grippy, though some find it too lively in rough sections. The bike is compared to models like the Specialized Enduro and Cannondale Jekyll, highlighting its position in the competitive enduro market.

Pros
  • Modern enduro geometry

  • Efficient to pedal up hill

  • Good value for money

  • Active suspension delivers masses of grip

  • Impressive parts spec for the price

Cons
  • Heavy

  • Not intuitive out-of-the-box

  • Suspension was too lively in rough sections

  • Limited seatpost insertion

  • High weight affects maneuverability

Key Quotes
It dived in and out of a snaking section of steep, supported corners in a solid, predictable manner and the dimensions felt good.

Unlike its more expensive competitors however, Polygon skips many of the fancier features to help lower the price point.

Polygon once again delivered an impressive bike for the money.
Loam Wolf logoLoam Wolf
All of that adds up to a not-insignificant 39.25 pounds (17.8 kg) – Collosus seems like a very fitting name given those numbers.
