noticed i have some play in the bb on the bike and of course i will replace it,it says UN51 68mm-113mm and its an octalink too,does this sound like the right one for the bike?cheers :?
A UN51 is square taper. Anything Octalink is prefixed ES rather than UN, so something doesn't add up there. What's the chainset - a serial number would help to work it out.
