Summary
The Polygon Collosus is praised for its modern enduro geometry, providing a planted and stable ride that excels in high-speed descents and corners. It offers impressive value for money with solid build kits and efficient suspension that delivers good traction and pedal performance, though it is often noted as heavy, which can hinder playfulness and climbing agility. While the bike requires careful setup to optimize its potential, it is a capable choice for rough, gravity-focused trails.
