A practical choice for replacing a compatible JIS square-taper bottom bracket on a bike with a 68 mm threaded shell, including 8bar SUPER and SUPER Gravel cranksets.
The VP VP-BC73 is a threaded bottom bracket with a JIS taper for compatible square-taper cranksets. Its 68 mm shell width and BC1.37” × 24T thread make it suitable for bikes using this traditional threaded standard, while the available 107 mm and 118 mm spindle lengths let you match the axle position to your crankset and frame setup.
Inside, sealed cartridge bearings keep the bearing unit contained for a clean, practical replacement solution. The axle uses boron steel, with cold-forged steel cups, phosphated cups and an anodised sheath for the specified construction and finish.
This model is listed as suitable for 8bar SUPER and SUPER Gravel cranksets. Before buying, confirm the crankset interface, bottom-bracket shell width, thread specification and spindle length; the correct spindle length is essential for proper chainline and crank clearance.
