The Polygon Tambora A4 gravel bike offers the ultimate balance between on-road speed and off-road control. This impressive gravel bike is designed for adventurers who do not want to compromise. Combine quick acceleration effortlessly with reliable control and push your limits on every ride!
Versatile frame concept
The robust aluminium frame of the Tambora A4 stands out for its innovative geometry that balances stability and speed. The bike's design includes flip chips, which are small metal inserts in the frame that allow you to physically change the position of the rear axle. Simply flip the asymmetric block to make the wheelbase longer or shorter and instantly make the bike more agile for the road or more stable for rough gravel terrain.
Optimal control with the GRX groupset
For the drivetrain, Shimano's GRX 2x11-speed groupset has been chosen, which gives the Tambora an impressively wide gear range. The combination of a 48-31T crankset and an 11-34T cassette allows you to achieve high speeds on flat roads as well as smoothly conquer the steepest hills. The hydraulic disc brakes offer reliable stopping power with excellent modulation, even when cycling in pouring rain or navigating through dusty potholes. They allow you to maintain full control of your speed and safety in all weather conditions.
High-quality finish and tyre selection
This gravel bike comes with 32 mm wide tyres as standard, which is ideal for high speeds on paved roads and light gravel paths. That said, if you want to explore somewhat rougher terrain, the Tambora A4 can accommodate tyres up to 45 mm in the long wheelbase position. The frame features several mounting points that make it easy to add accessories for multi-day bikepacking adventures. The robust wheelset and ergonomic handlebars complete the picture for riders who need comfort and durability on unfamiliar trails.
