Drawing inspiration from the birth of bicycles, sparked by the largest volcanic eruption in recorded history, Mount Tambora, we've looked back and reminded ourselves and the world of this history by creating the Polygon Tambora G – a perfect fusion of gravel and all-road capabilities in one extraordinary ride. This bike empowers us to conquer any terrain with newfound speed.​Whether you're a competitive racer, long-distance enthusiast, or an adventurous explorer, this bike is tailored to meet your needs.
