Is it a square taper BB you need? if so......

I might have an almost never used one, as i went back to fettling an old Gary fisher MTB that I haven't touched for about 4 years, I think I replaced the old BB back then, to accommodate a different crankset as I was struggling for a correct sized BCD replacement ring, and then barely rode it.

looking at it again last weekend, I've put the original crankset back on with a new ring from SPA, but with the 73 122mm BB in there (Shimano un55), the chain line is all wrong, it really needs a 110mm / 113mm, and a 113mm arrived this morning, so will try that at weekend (no stock of 110mm in 73mm).

I don't think any other bike I have has a 73mm shell and square taper cranks, so the 122mm is probably surplus to requirements. if looked very new when I removed it, the grease around it was even clean!!
