Polygon Strattos 7 Di2 Carbon Endurance Road Bike
The Polygon Strattos 7 Di2 is a modern carbon endurance road bike designed for cyclists who want speed, comfort and electronic shifting at an excellent price. Its carbon frame and fork are combined with Shimano 105 Di2, hydraulic disc brakes and tubeless-ready wheels to create a capable bike for training, group rides and long-distance cycling.
Comfort-focused endurance geometry places the rider in a more natural position, helping to reduce strain on the back, shoulders and hands. Carefully shaped seat stays improve compliance over rough surfaces while retaining the responsive feel expected from a performance road bike.
Carbon Endurance Frame and Fork
The lightweight carbon endurance frame provides an effective balance of stiffness, comfort and low weight. A matching carbon fork improves steering accuracy while helping to reduce vibration from uneven road surfaces.
Streamlined internal cable routing creates a clean appearance and protects the brake hoses and electronic wiring. The frame also uses a modern T47 threaded bottom bracket and UDH derailleur-hanger standard for easier maintenance and future compatibility.
Shimano 105 Di2 Electronic Shifting
The Shimano 105 Di2 2x12-speed drivetrain delivers fast, accurate and consistent electronic gear changes. Shifting requires minimal effort and remains precise during hard acceleration, climbing and long rides.
A compact Shimano 50/34T crankset is paired with an 11-34T cassette, providing suitable gearing for fast road riding, rolling terrain and steep climbs.
Comfortable Endurance Geometry
The Strattos 7 Di2 features a higher stack and optimized reach to create a comfortable endurance riding position. This helps reduce fatigue while maintaining responsive handling and efficient power transfer.
Seven available frame sizes, from XXS to XXL, allow riders between approximately 151cm and 195cm tall to find an appropriate fit.
Hydraulic Disc Brakes
Shimano 105 hydraulic disc brakes provide strong and controlled stopping power in dry and wet conditions. Shimano RT54 160mm Center Lock rotors offer dependable braking during fast descents and changing road conditions.
Tubeless-Ready Wheels and 30mm Tyres
The Polygon RD6 Disc wheelset features alloy double-wall tubeless-ready rims and sealed-bearing thru-axle hubs. Schwalbe One Addix TLE 700x30C tyres provide a fast and comfortable ride with dependable grip.
The frame accepts tyres up to approximately 34mm wide, giving riders the option to increase comfort and confidence on rough roads. A complete tubeless conversion may require suitable rim tape, tubeless valves and sealant.
