So last night I took the opportunity, whilst waiting for a Tesco delivery (they said between 7 and 9 so I was home for 7 – they turned up at ten-to 9), to install my Campagnolo Record bottom bracket. I’d already purchased a tub of grease and the special Campagnolo Record bottom bracket tool so we were ready to go.
The whole thing was a little trickier than I’d expected, and before you ask, yes I did have the correct size bottom bracket for the bike – all measured and verified by my local shop / Sheldon Brown website.
As I was tightening the brackets it was getting pretty stiff and to make sure that I could undo them if needed I did. When I removed the BB I found that the very top of the threading on the cartridge had been worn off creating a steel thread. Fortunately this hadn’t damaged the cartridge by more than a fraction of a mm.
However, it still took approximately an hour or so to tighten the cartridge sufficiently.
I’ve briefly tested the BB with my cranks and it turns beautifully and smoothly.
