Endurance road for long distances

Strattos C is designed for long days in the saddle and long-distance adventures where comfort and efficiency come first. Clearance for up to 34c tyres and dropped seat stays reduce road vibration without losing stiffness; relaxed geometry makes every endurance ride a pleasure.

Versions in the Strattos C range: STRATTOS C9 AXS · STRATTOS C8 Di2 · STRATTOS C7 Di2

Polygon Strattos C

Key features

01

Smooth ACX carbon frame

The ACX carbon layup is tuned to be both light and vibration-damping, so you can ride longer with less fatigue than on a stiff race frame.

02

34mm all-road tyre clearance

Fit tyres up to 34mm and run lower pressures for more grip and comfort — from tarmac to light gravel.

03

LINC semi-integrated carbon cockpit

Aerodynamic internal routing that is easy to maintain and adjust.

04

SRAM UDH derailleur hanger

Compatible with hangerless SRAM Transmission drivetrains; replacement hangers are easy to find in most bike shops.
