Polygon Bend R7 Bronze Gravel Bike
The Polygon Bend R7 is an adventure-ready gravel bike built for riders who want to explore beyond normal roads. Its durable ALX alloy frame, carbon fork, wide tyres and stable geometry create a comfortable and capable platform for gravel riding, bikepacking and mixed-terrain adventures.
A SRAM Apex 1x11-speed drivetrain provides simple and dependable shifting, while hydraulic disc brakes deliver reliable stopping power. The addition of a 70mm dropper seatpost gives the rider extra control and freedom of movement on steep or technical terrain.
ALX Alloy Gravel Frame
The ALX alloy frame is designed to balance durability, comfort and responsive handling. Its gravel-specific geometry provides stability on loose surfaces while remaining efficient and comfortable during long rides.
Multiple mounting points allow riders to carry bottles, bags and bikepacking equipment. This makes the Bend R7 suitable for daily gravel riding, long-distance touring and multi-day cycling adventures.
Carbon Rigid Fork
The carbon fork helps reduce weight and absorbs vibration from uneven roads and gravel tracks. It also provides accurate steering and confident control across changing terrain.
SRAM Apex 1x11-Speed Drivetrain
The SRAM Apex 1 drivetrain uses a single 40T chainring and an 11-42T cassette. This provides a useful range of gears without the additional complexity of a front derailleur.
The simple 1x11-speed configuration is easy to operate and provides dependable chain retention when riding over rough surfaces.
Hydraulic Disc Brakes
SRAM Apex hydraulic disc brakes provide strong and controlled stopping power in dry, wet and dusty conditions. SRAM Paceline 160mm Center Lock rotors deliver dependable braking for fast gravel descents and loaded bikepacking trips.
Wide Tubeless-Ready Tyres
The Bend R7 is fitted with Vee Rocketman 700x44C tubeless-ready tyres. Their wide profile improves comfort, grip and stability on gravel, broken roads and compact trails.
The frame provides clearance for tyres up to 50mm wide, allowing riders to select a tyre setup that suits their terrain and riding style. A tubeless conversion may require suitable valves, rim tape and sealant.
70mm Dropper Seatpost
The TranzX dropper seatpost provides 70mm of travel. Lowering the saddle gives the rider more space to move over the bike, improving confidence and control during steep descents and technical sections.
Flared Gravel Handlebar
The 16-degree flared alloy handlebar provides a stable and comfortable hand position. The wider lower section offers additional control when descending or riding over loose and uneven terrain.
