The Tambora also makes the perfect racer-all-rounder with multiple mounting points for bottle cages, racks, mudguards and just about anything else you need to carry.

Buy One, Plant One
Since January 2020 we have worked with not-for-profit reforestation partners to donate enough money to pay a local person a fair wage to grow, plant and guard to maturity 1 native tree for every bike we sell.
We've now planted more than 395,000 trees and counting.
