Hi All,

I'm looking for 107x73 bottom bracket. Ideally a Shimano BB-UN91 in good condition or UN51 eventually. Thanks to let me know if you've one in one of your spares boxes...

Cheers,
Fred

Sorry, stash only yielded 113 versions.

I did find a middleburn one but that measures up at around 110 ish. Shorter than the royce I have which is 113, but longer than 107.
 
107x73. Bearings smooth.
