Description

GEOMETRY

To create a natural and comfortable riding position, Polygon designed the Cascade with a 73° seat tube angle and a tall stack height for a comfy/upright riding position complemented by a relaxed 69° head tube angle.

LIGHTWEIGHT ALLOY

Aluminum has been the go-to material for bikes since the late 90s. Polygon uses an aluminium blend that is lighter and more durable than its peers. Featuring 6061, triple-butted, heat-treated tubing for strength and durability, ALX was built to last.

100MM FORK

The XCE 28 coil spring fork from SR Suntour features 100mm of travel and a quick-release interface for a smooth and controlled ride.

SHIMANO 3x7

Shimano 3x7-Speed gears offer the range and durability you need to tackle just about any terrain. Not only is Tourney tough, but is simple to maintain and repair.

Assembly

Your bike needs minor assembly before riding; use the tools and videos included.

As a guide, it'll take 10-40min depending on whether you're an experienced bike assembler or have little to no mechanical experience.

Side Note: Your cables will stretch during the initial bed-in period and must be adjusted by an experienced mechanic around 150km of riding.
