Simon- many thanks for this. When they were changing the tyres recently I noticed that the wheel had a type of plate which had studs on them. Would these be "swappable" or is there an adaptor plate of some type required.
To be honest Taffy, I'm not 100% sure - it sounds like a hub adaptor. I am pretty sure that is how MMC went from from centre lock to 5-bolt; I know it wasn't a significant modification to the Aero S1.
