FRAME AND FEATURES

Polygon uses a 6061 ALX hydroformed and triple-butted aluminum frame on the Collosus lineup. Internal cable routing is secured at the ports to help prevent rattle, keeping this alloy steed looking clean. The derailleur cable leaves the front triangle, entering the driveside chainstay before exiting just before the rear axle. On the non-driveside, the brake hose is left exposed but secured and tucked nicely behind the chainstay, maintaining the clean aesthetic Polygon was going for.

The N7 also has downtube frame protection features, with a shuttle pad near the headtube and a bash guard near the bottom bracket. The chainstay has a guard to protect the tubing and keep chain rattle on the quieter side. Frames come in four sizes, from small to X-large, and the color is velvet cake red.

SUSPENSION

For the Collosus, Polygon switched things up from the suspension platform found on their Siskiu bikes. Independent Floating Suspension (IFS) is Polygon’s six-bar suspension design, found on these big rigs. Predictability is the goal for IFS as the N7 goes through all 170mm of its travel while also focusing on pedal and braking forces, pedaling efficiency, and wheel path control.

GEOMETRY

A slack 63.5° headtube is paired with a reasonably upright 77° seat tube to keep the rider in a comfortable pedaling position. The N7 has a BB height of 353mm, with a drop of 27mm, and chainstays are consistent across all sizes at a compact 435mm for its 29” wheel.

Reach increases a steady 20mm across frame sizes, starting at 440mm on a size small and topping off at an even 500mm on an X-large. Our size large on test has a reach of 480mm. The wheelbase on a large is 1266mm. Frame Stack jumps up from 621.9mm on a small to 639.8mm on the X-large, with our size large’s stack measuring 634.1mm.

Riders’ dreams aren’t limited by the depth of their pockets. The latest evolution of the Siskiu T series opens up any trail to any rider through encompassing progressive geometry into an attainable package with a water bottle space!

On the trail, the Siskiu T feels just as responsive and agile as the previous generation but the overall ceiling of what the bike is capable of has been lifted. The Siskiu T handles the demands of a modern trail bike, striking the balance between high-speed control and playful handling. Designed around our Wheel Fit Size System, 29” models feature 135mm of rear travel with 140mm forks whilst 27.5” bikes have 140mm in the rear with 150mm up front. Seat tubes have been significantly shortened to allow for 150mm dropper posts on the small and medium frame, 170mm on large and XL. The chainstays were shortened to keep the bike fun but also ensure that the overall wheelbase isn’t too long for general trail riding.

The Siskiu T utilizes the tried and tested FAUX BAR design. The linkage is built around the One Piece Unibody Pivot Bridge that reduces the frame’s weight but also improves stiffness and reduces lateral flex on the rear shock under load. The kinematics of the bike maintains the poppy supportive nature of the previous generation while improving the climbing efficiency and small bump compliance.If you’re looking for a bike to do it all with killer style and a dependable, high quality, trail-ready components list – Siskiu T is the right choice for you. For any trail, any rider.
