The Polygon Strattos S3 2025 is a lightweight endurance road bike that upgrades the Strattos formula with a full Shimano Sora 18-speed groupset. The ALX All-Round aluminium frame offers a comfortable, stable riding position, while the lightweight carbon fork smooths out rough tarmac. Shimano Sora ST-R3000 dual control levers deliver light, precise shifting through a 2x9 drivetrain, with a Shimano Sora 50/34T compact crankset and an 11-28T cassette for efficient gearing on rolling routes. Tektro R315 caliper brakes give dependable control, and 700 x 28C tyres on double-wall alloy rims offer comfort without sacrificing speed. The Polygon Sport alloy drop bar provides several hand positions for long rides. Available in sizes S to XL in Brown, the Strattos S3 is ideal for riders who want quality components for regular training, weekend rides and sportive events.
