Hi all,
I'm looking for a bottom bracket 73mm shell size, 122.5mm or 127mm spindle length, 1.37 x 24 for a build i'm doing.
I bought a shimano UN300 but cannot get it to thread into 2x different bikes, the threads look fine on it, so not sure what's happening, but have seen video's pf others having the same issue. A BB UN71 i have screws straight into both bikes, so i know the bike threads are fine.
So decided to look for an NOS or used older BB in good condition, i would like a shimano but open to other brands, if anyone has a BB in these specs they want to sell.
Thanks in advance.
