THE FRAME AND FEATURES
Suspension Platform – Built using Polygon’s 6061 ALX triple butted and hydroformed aluminum, the 170mm Polygon Collosus N7 features their IFS six-bar suspension platform. Independent Floating Suspension or IFS is designed to offer a very neutral and predictable feel throughout the travel. Extra energy was spent controlling the wheel path, pedaling efficiency, and separating input forces from braking and pedaling.
Here you can see that two small links are connecting the front triangle to the chainstays. This portion of the platform controls the rear axle path. Separately, you can see the seatstay connecting to a small rocker link, which drives the shock and controls the leverage rate independently.
FRAME | Polygon gives the Collosus internal cable routing for all in the front triangle, and in the chainstay for the rear derailleur, but opted to run the rear brake outside the chainstay. Frame protection features include a nice shuttle pad on the upper portion of the downtube, as well as an armor plate near the lower portion of the downtube for rock and bash protection. Other frame protection includes a ribbed chainstay protector, although we wish it was a bit longer for more coverage up near the chainring.
GEOMETRY | Polygon says their Collosus enduro bike line is “Designed to be tough.” With thoughtful choices around spec selection and geometry, the Collosus does appear to be geared towards the burly end of the spectrum. Available in four sizes from Small to XL, we’ve opted to review the size Large after this Dissected feature is complete. The Large comes with a 480mm reach, short 435mm chainstays, an overall wheelbase of 1,266mm and a stack height of 634mm. The angles sit right in the sweet spot for enduro rigs with a 63.5-degree head tube angle and 77-degree effective seat tube angle.
