POLYGON COLLOSUS N7
Regular price OMR 1,150
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.
BUILD SPECS
Polygon does a decent job of balancing overall price and value. For suspension, a base-model Rockshox Zeb is paired with a Rockshox Super Delux Select +, both set at 170mm of travel. Shimano takes care of most of the 12-speed drivetrain, with a Deore M6100 derailleur and shifter. Shimano MT150 cranks and 32T chainring work with a Sunrace CSMZ800 11-51t cassette and a KMC X12 chain to keep the N7 rolling.
Tektro is in charge of stopping the Collosus N7, with 4-piston/2-piston caliper front and rear HD-M735 brakes and 203mm rotors. A WTB Volt saddle sits on top of a TranzX dropper post, with 170mm of travel for large and X-large, and 150mm for small and medium. Aside from the Vee Flow Snap 2.6 tires, most other components are Entity, Polygon’s in-house brand. This includes the 32-hole and 35mm inner width Entity wheelset, 35mm stem, and 780mm handlebars. Total bike weight tipped the scales at 39.1lbs/17.7kg for our size Large.
