Box Two™ External bottom brackets feature cold-forged, CNC-machined alloy cups, dual-labyrinth bearing covers, and precision sealed bearings. The 24mm variants are the perfect match to Box Three™, Four cranks, and the ultimate upgrade to the budget BBs sold with most cranksets. Box Two™, 24mm External Bottom Brackets, are designed to fit all 24-millimeter crank spindles and frames with 68 or 73 x BC 1.37-inch bottom bracket shells.

Also available in a 30mm version, The Box Two M30 bottom bracket is a slightly less acute embodiment of Oversized technology seen in the M35. Generously sized ABEC-5 bearings help reduce power loss to defection. The larger 30mm cross section is designed to mate up with the rest of the M30 line of Oversized crank sets. (30mm on one side with a tapered 28mm on the other end)
