A suitable choice for owners of compatible 8bar SUPER or SUPER Gravel cranksets who need a replacement English-threaded, JIS-taper bottom bracket.
The VP VP-BC73 is a 68 mm English-threaded cartridge bottom bracket for compatible JIS-taper cranksets. Its sealed cartridge bearings are housed in cold-forged, phosphated steel cups, while the axle uses boron steel for a durable drivetrain interface. An anodised aluminium sheath completes the assembly.
Choose the spindle length that matches your crankset and frame setup: 107 mm or 118 mm. The VP-BC73 is listed for 8bar SUPER and SUPER Gravel cranksets, with related variants available for a chain guard stay mount plate, front derailleur bottom-bracket mount plate or chainline stopper ring.
