Features

Fits 68 and 73mm shells. Threads into BC1.37in Euro bottom bracket shells in either width, so it suits most frames set up for an external bottom bracket.
Made for 24mm spindles. Takes any 24 millimetre bottom bracket spindle, so a modern crank drops straight in.
Dual-labyrinth bearing covers. The covers keep water and grit away from the bearings, so your cranks keep spinning freely for longer.
Cold-forged alloy cups. Forged then CNC machined, so the cups thread in cleanly and sit accurately in the shell.
A step up from stock. Precision sealed bearings replace the budget bottom brackets that come packaged with most crank sets.
