I have just gotten back to tinkering with my twenty after a hectic quarter of tests, papers, and all that is college life, but have once again run into the same problem I ran into months before:
the bottom bracket
I tried not one, but two spindles in the hopes that I could reuse the cups, to no avail. I tried various bearing-spinndle combinations, to no avail.
I have in my possession a Shimano UN72, but after much hammering, I think I messed up the bearings. It does not turn freely.
I thought about the Phil Wood retaining rings, but $47 + shipping is quite steep.
But all is not lost! I went to my LBS (one of many!) http://www.richardscyclery.com/ and they said that they could reface the bottom bracket from 76mm to 73 and retap it to 24 TPI easily. Just out of curiosity, I think I'll ask what will happen if it is refaced to 68mm......
So now I pose a question to all those who have gone before me with the Raleigh Twenty Bottom Bracket:
Retap or not to retap, that is the question!
