Might be a simple question but,

If a cup and cone spindle measures 120mm, is there/it possible to use a 118mm BB with spacers 1mm on each side?
Someone with the same bike said "122.5mm was to big".

It's a cheap bike and uses a 120mm cup/cone BB, and a "prowheel jazz" crankset, the crankset is bent and the bearings are clicking/crunching while peadling.

I would like to replace it with a shimano un55 63x118mm BB?/ Shimano Acera M361 crankset.

Is this possible/ any ideas?
