Stepping up to a 2-piece crankset is one of the biggest upgrades a racer can make — stiffer, lighter, and far easier to install and service than old-school 3-piece designs. The Box Four 2-Piece Crankset brings that upgrade within reach. Its oversized bottom bracket interface and flex-resistant spider put your power into the track instead of losing it to twist, so you get a snappier launch out of the gate and stronger drive down every straight. Everything you need is in the box, making it a clean, no-surprises install for a race build or an upgrade to a stock bike.
