Well hello!

I have been reading the archives and trying to gather as much information as I can regarding upgrading a Peugeot to a fixed gear bike. I know a fair bit now, but would like to know the answer to this question before I do anything more.

I came across a very good condition Peugeot UO8 frame, just the frame, and want to build it up into a fixed gear bike. I also wanted to try and use the Shimano UN72 with Phil Wood cups for the new bottom bracket. I have been able to track down a UN72, but it is 73mm x 107mm. Will this fit on my Peugeot?

I understand that these are rather hard to come by and didn't want to disregard this until I knew for sure it wouldn't work.

Thanks for any help you can provide
