As I have a number of shimano chainrings already and I like that you can have compact, semi compact and man sized on the same chainset im looking at the quarq dfour, at £808 from powermeter24, I've looked at the p2m ng option but it seems to end up much more expensive by the time you factor in cranks, a charger, chainring bolts and the tool to put the whole thing together, is there anything else I should be looking at?
Both bikes it might go on are 68mm standard bottom brackets and I have a number of Gxp bottom brackets knocking about so compatibility and the occasional switch between bikes shouldn't be a problem.
I presume if I bought a new bike with bb30 I could just use a converter to use gxp?
