Hand-built in Southern California, Box Three™ Wheels are made with Box One™ front rims and 36-hole, Box Two 20mm Front Hub laced 3-cross front with 14-gauge stainless steel spokes and brass nipples. The Box Two 20mm Front Hub is perfect for those looking for ultimate stiffness and power transfer. When paired with a 20mm fork, this hub and thru-axle system provide a solid connection where lateral deflection is minimized so you can get all the power to the ground and put down quicker gates and faster laps. Each wheelset is built with Wheelsmith Spoke Prep and inspected using a DT Swiss tension meter for quality control. 20mm front axle is included.
