The new Polygon Colossus DH9 frame and suspension system has been carefully redesigned by the engineers at Polygon and with intensive feedback from the UR Team racing the DH World Cup Championships. In particular, Australians Mick Hannah “Sik Mik” and Tracey Hannah had a pivotal role in creating this new frame, with now better traction over rough sections, better pedalling efficiency, and a more precise steering feedback. The rear suspension system is now more progressive and the shock ramp up has been fine tuned. To increase rear end stiffness, the rear triangle is now made out of Polygon’s proprietary ACX Carbon, which was moulded and shaped to be extremely stiff laterally, soak up small vibrations and bumps better, keeping the rear wheel grounded for better traction, and also the added benefit of shedding weight from the frame. Testing wheel sizes was also a huge deal in making the Polygon Collosus DH9 frame, with Polygon testing 26”, 27.5” and even 29” wheels. In the end, 27.5” wheels (or 650b) were the clear winners, offering extra speed on the flats, soaking up the punishment of rock gardens with ease and allowing to build a super nimble bike to tackle the most demanding technical sections in the Downhill World Cup calendar.
The frameset is also supplied with the Top of the Line Fox DHX2 Factory rear shock. With it's Kashima stanchion, new and improved Rebound and Compression adjustments, the DHX2 sets a new benchmark for Downhill performance. Shock Springs are also framesize sensitive, with Small and Medium frames supplied with a 350 lbs, Large frame with 400 lbs spring and the eXtra Large frame 450 lbs.
