I'm next to buy '06 Cannondale Six13 Team 1 Compact Drive and got 1 question concerning BB30 crankset. Is it possible to replace 50-36 chainrings to regular one's 53-39 e.g. Shimano Dura-Ace? Does anyone know the exact params of this crankset?
The thing is that I don't need compact chainrings, because we mostly have flatlands. The best way will be replacement of the whole crankset
if you're referring to the alloy Si cranks, you can get a 130BCD spider from cannondale which will let you use standard 39/53 rings. replacing those cranks with anything else is heresy! also, if you're already talking about replacing the cranks, why not just get the standard double Si cranks instead of going through the trouble of installing the adapter, buying other (inferior, but not by much), cranks. also, once the adapter is installed, you can't really take it back out again without a special press. also, you will need special tools to remove the Si crankset.
