Opinions I have so far received on the issue of a cart BB for the 75.
CONdor (Keith): Miche. Not sure of the taper, but it is adjustable.
CONdor (Adri): UN53 110mm JIS.
Mosquito: Sugino RD 103mm JIS.
Will (Hubjub): UN53 107mm JIS or Phil Wood 108mm JIS (adjustable).
Royce: send in the cranks and they'll spec the BB to suit.
Terry Dolan : Campagnolo Mirage/Centaur/Pista 111mm ISO.
ALL: just get the 75 cup 'n cone.
So there you have it.
No fecker has the definitive answer.
I have built up the 75 onto the Campag BB, but not ridden it (regular readers will know of the Dolan saga...).
It looked right. Chainring clearance looked ok, a quick check with a straight edge before I took it all apart showed it all to be lined up correctly.
Whether or not it would have wotked when I tried to ride it is something I can't comment on.
I'm still undecided what to do when I build the new bike, but the Campag option is the front runner.
Most likely I'll buy the cheapest Campag (less than a tenner) and see if it fits. If it does I'll swap it out for a better one. If not I'll go with the 107 UN53. If it still doesn't work I'll have to consider shelling out on the Phil.
Or I'll just go down the pub.
