	S	M	L	XL
Height (In cms.)	155-165	165-175	175-185	185-195

Source: Polygon per-model geometry tables (polygonbikes.com). Polygon also publishes a separate generic sizing guide with wider, overlapping bands; the figures above are the ones Polygon lists against these specific models.

The Polygon Collosus N7 29" Mountain Bicycle 2025 is built for technical climbs, steep descents and aggressive trails. Its modern geometry provides stability at speed while retaining climbing efficiency.

Independent Suspension Control: The ALX alloy frame uses Polygon’s IFS six-bar suspension platform with 170 mm of rear travel. It reduces braking influence on suspension movement for better traction over rough terrain.

Long-Travel RockShox Setup: A 170 mm RockShox ZEB fork absorbs large impacts and supports confident steering on demanding sections. The 29-inch wheels improve rollover and stability over rocks, roots and obstacles.

Deore-Powered Performance: The Shimano Deore 1x12-speed drivetrain offers a wide 10-51T range for steep climbs and fast descents. Four-piston hydraulic disc brakes and Maxxis Assegai tyres provide strong control.

The Polygon Collosus N7 29" Mountain Bicycle 2025 delivers long-travel suspension, stable handling and durable components for riders ready to take on serious enduro trails.
