No. 9 MCX ForkDescription The Whisky No. 9 MCX monster cross fork brings extra wide tires to your drop bar bike. How wide? The MCX accommodates tires up to 700c x 51 mm or 650b x 61 mm (thats 2. 4). A relatively short 415 mm axle to crown minimizes the geometry effects of a larger fork, and a 50 mm offset improves toe clearance with large tires or fenders. The design draws from our CX forks, with lightweight carbon construction, a 12 mm thru axle, and flat mount
