The Polygon Tambora Series represents a versatile range of gravel bikes designed to handle a mix of terrains, from smooth tarmac to rough gravel roads. Built with the adventurous rider in mind, the Tambora bikes are ideal for those looking to explore beyond the beaten path, offering a perfect balance of performance, comfort, and durability. Whether you’re commuting, bikepacking, or just looking to explore new routes, the Tambora Series provides a capable and enjoyable ride.

Engineered for Adventure

The Tambora Series is crafted to deliver outstanding performance across various surfaces, thanks to a combination of high-quality frames, reliable components, and thoughtful design. Each model in the series is built with specific features to suit different riding needs, whether you’re a seasoned gravel enthusiast or new to off-road riding.

• Alloy and Carbon Frames: The series includes models with lightweight alloy and carbon frames, providing a robust yet agile structure that absorbs vibrations from rough surfaces, enhancing comfort over long distances. The carbon frames offer a stiffer and lighter alternative, perfect for riders prioritising speed and efficiency on mixed terrains.
• Versatile Geometry: The Tambora’s geometry strikes a balance between speed and comfort, with a more relaxed position compared to road bikes, allowing riders to stay comfortable during long rides. The slightly slacker head tube angle provides stable handling on uneven terrain, making it easier to navigate technical gravel paths and loose surfaces.

Optimised Components for Every Ride

The Tambora Series is equipped with a range of drivetrain and component options to cater to different riding styles and preferences:

• MicroSHIFT Advent X 1x10: The Tambora G4 model features a MicroSHIFT Advent X drivetrain, a reliable 1x10 setup that offers a wide range of gears suitable for various terrains. This setup is ideal for those who prefer simplicity and low maintenance, providing smooth and consistent shifting in all conditions.
• SRAM APEX and RIVAL AXS: The higher-end models, such as the Tambora G7 and Tambora G8X, feature more advanced drivetrains with 1x12 gearing systems from SRAM, including the RIVAL AXS wireless setup. These drivetrains deliver precise, effortless shifting and a broader gear range, making them perfect for tackling steep climbs and fast descents alike.
• Carbon Forks for Comfort and Control: Each bike in the series comes with a carbon fork, which significantly reduces weight while enhancing ride comfort by absorbing road vibrations. The fork's stiffness also improves steering precision, allowing riders to maintain control on technical sections of gravel or loose dirt.

Designed for the Modern Gravel Rider

The Polygon Tambora Series is designed to meet the demands of modern gravel riding. With wide tyre clearance, these bikes can accommodate larger tyres, allowing riders to adjust for different terrain types, from faster road tyres to wider, more grippy options for off-road riding. The versatile frame design also includes mounts for bikepacking gear, such as racks and extra bottle cages, making the Tambora ideal for longer adventures or overnight trips.

The internal cable routing keeps the bike’s aesthetics clean while protecting cables from dirt and debris, which is especially beneficial for off-road environments. This design choice not only improves the bike’s overall look but also enhances its durability by reducing maintenance needs.

Perfect for Multi-Surface Exploration

Whether you’re commuting to work, tackling a weekend adventure, or planning a multi-day gravel tour, the Polygon Tambora Series provides the versatility you need. Its mix of lightweight construction, reliable components, and comfortable geometry ensures that each ride is both efficient and enjoyable, no matter the terrain.
