So IRD goes to all the trouble to make a beautiful copy of the Campagnolo cranks and they make them with a144 bcd. ???? Short sighted, in my opinion. Just imagine how many more crank sets they could have sold with a 130 bcd.
The chainset is for 'track' (urban fixie) use, it's supplied with one 46t ring, and doesn't appear to have an inner ramp for an inner ring.
I have just had to buy a replacement 45t 3/32nd 144 bcd ring for my Superbe Pro track chainset which has ended up on my town hack bike (for shame) and it was a bit of a pain as there is a premium charged for that size.
