OK cranks got. I had the patience to wait and see exactly what BCD they were. They are indeed 135. Also, due to the way they bolt to the cranks, you have to either run two rings or mess around with spacers. I will explain this with pics at another time, but for now I had a plan any way.

Just put that on. It also gets around another "issue". See, Campag colours are silver and silver. To buy a black one? you need to spend about 45 quid. So I got this.

The pair cost me 40.50p. So still less than a 42t in black (44 cost even more) and the silver will be sorta hidden. I also won't have to worry about the chain eating my trousers lol. It will also go straight on, without needing to piss with spacers and etc.
