Shimano BB-6500 Octalink V1 Bottom Bracket 68mm/118.5mm
Notes from MyBikeThing The BB-6500 represents Shimano’s engineering excellence in their Octalink V1 system, featuring precision-machined aluminum cups and a chromoly spindle. What sets this apart is its sealed cartridge design that helped define the modern bottom bracket standard.
Condition Housing shows typical cosmetic wear with some surface marking. Bearings rotate with noticeable roughness but remain functional. All threading is clean and undamaged, lockring intact.

Workshop Wisdom Always check your frame’s shell width and threads before installation. Pro tip: A light coating of anti-seize on the threads prevents future seizure issues common with aluminum cups.
