If you're looking for a stiff fork for your custom hardtail or a dedicated ripper, the Whiskey No. 9 MTB Fork is certainly a worthy choice. With tire clearance up to 29 x 3. 0 inches or 27. 5 x 3. 25 inches, it breathes new life on hardtail mountain or more bikes while absorbing trail light when the going gets rough. The fork is constructed from unidirectional carbon fiber for reliable strength at a low weight, and features a tapered head tube and thru-axle outputs for responsive, confident steering. This particular model fits hubs with 15x100mm axles. If you're looking for a rigid fork with Boost 15x110mm spacing, check out the Whiskey No. 9 Boost LT Fork
