• As above, I have a Campag Mirage 170 52/39 chainset and was going to ask about chain rings, cogs, and wheels.

    Can I dissassemble the chainset and put it back together with one of these...

    ...to sort out the chainline? The Velosolo chainring has the advantage of different widths.

    Is there an advantage having a specific fixed wheel as opposed to a standard road wheel with spacers?

    I've ben UTFS and coming up with oblique references to this sort of info.
