Overview
The Warakin redefines the all-road category. Where traditional all-road bikes have tire clearance up to 700c x 40mm, the Warakin takes it up to 700c x 50mm. If a bike is truly meant to ride all roads, it needs to fit the tires to allow you to ride confidently, with comfort, and as fast (or slow) as you’d like
