Hi,

Just bought a vintage road frame to build up as a fixed, but the bottom bracket shell measures 65mm wide. Will a modern 68mm BB work ok (possibly one with some adjustment, ie. Miche / Phil), or am I going to have to go elsewhere? It's currently just got some old Campy cups in it.

Cheers in advance,

iBob

I had the same situation on the bike I just built up - I bought a Shimano cartridge BB to replace the worn out old 3 piece cup & cone set up, but found that with the cartridge screwed in it's not possible to snug down the left hand cup because of the undersize width. I used the lockring from the old adjustable cup as a spacer on the right hand side - worked a treat.

great idea.
Any one know what shells where 65 mm? An old proprietary size I presume?

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

For syntax highlighting, surround the code block with three backticks:

Just like Github, a blank line must precede a code block.
