I'll be ordering the remaining parts to switch my 06 Poprad over to campy, but now need to decide on what crank to use. Im putting centaur rd, fd, and shifters on the poprad, but Im unsure about the crank. I haven't been able to find smaller outer chainrings for campy cranks, so are they available? I'd prefer to just use this crank, as it would save some money and I like the look of the silver. Thanks.
