The Box Four Crankset features a 2-piece design with an oversized bottom bracket interface. The 24mm spindle is pressed into the drive-side crank arm for durability and easy installation. The non-drive side crank arm features a 2-bolt pinch system for added strength. Our unique 4-bolt 104 BCD spider features a flex-resistant ring for optimum performance.

Box Four Cranks feature steel pedal inserts that require pedal washers and external sealed bearing BSA bottom brackets, and both are provided in the box.

      Awesome crankset

      Awesome crankset for my son's race bike. Quick and simple install paired with a set of Box chain tensioners and Big Mak is back out ripping on the track! #PurpleHeartRacing

      This crank is on my class and cruiser. If I get a new frame this crank goes with me. I never had an issue with these cranks over the few years I Have used them. Use with confidence!
