A friend of mine has asked for some help from me, to fix his bike. It's an old knackered thing and the bottom bracket is shot and needs replacing. Now, if/when he tells me what speed system it is (6/7/8) how do i know which BB/axle length to source?
Made slightly complicated by the fact he lives in another town and will be dropping the bike off whith parts, so i can't measure the old BB beforehand.
It's been so long since i dealt with a square taper BB i've forgotten any knowledge i had about sizing them.
measure end to end of the shafts (ie longest length)
and the width of the bb shell of the bike
post up if you need help sourcing
That's the thing - i haven't got the part to measure!
I'd ask him to do it but he just looks blank when i mention parts etc 🙂
haha i see... il have a rummage for a diagram on google?
