The Evil Chamois Hagar turns conventional gravel biking on its head, blending mountain bike-inspired geometry with gravel performance. Boasting a slack 66.67-degree headtube angle, 430mm chainstays, and 80mm of bottom bracket drop, it offers stability and control like no other gravel bike. Its ample 700 x 50c tire clearance and extended reach redefine what’s possible on mixed terrain.
This highly adaptable ride invites endless customization, allowing you to tackle trails, gravel paths, or urban streets with equal confidence. The Chamois Hagar isn’t just a bike—it’s a bold statement on gravel riding's future.
