Can anyone advise me which bottom bracket I need for a Campagnolo Mirage 175 groupset? It's going onto an old Dawes Reynolds 531 ST frame.
The frame currently has a Shimano BB-UN100 bottom bracket, but it seems way off from being a good fit.
Thanks in advance!
As requested, here are some photos of my Campagnolo Mirage cranks:
Also, I was advised that this bottom bracket was the one I need:
which I have now bought, but there seems to be hardly any taper on it:
When I put the crank onto it, there is about an 10mm gap at the BB side:
and about an 8mm gap on the crank side.
Presumably, that's not a good fit?!
Maybe a spindle with a similar length but with a more sever taper is what I need?
I've now fitted the BB and cranks onto my bike. I've only done the crank bolts up hand tight, but I can't imagine they would slide on much further when fully tightened.
The problem I have now is that I cannot select the large chainwheel on the front. (I've fully adjusted the front derailleur, but it just doesn't have the necessary reach.)
So, pretty sure I have the wrong BB. Can anyone advise on my next move?
