    I have a Royce BB and Campag Nuevo record 42/52 Chainset the bb is the
    correct length for the chainset but without measuring it I am not sure of
    the BB actual length .
    I would like to fit a compact 50/35 chainset and keep the existing BB.
    Can any one help with a suitable compact chainset recommendation Keeping the
    Royce square taper BB

    You're not likely to find one, because modern cranks are all low profile,
    Your existing spindle is probably 8-12mm too long for a compact double. You
    might be able to find an old 110/74 touring crank that you could ditch the
    granny ring from.

    Something like this would probably work:

    I'd guess that your existing bb is a 111 or 114 x ISO taper bb. If
    that is correct, a Sugino XD crankset will work. I'd think that
    www.yellowjersey.org or
    <http://sheldonbrown.com/harris/cranks.html#11074> can put together
    what you want.

    Consider getting a crankset you want and changing the bb.

    If it's 111mm the new Centaur compact is propably also an option.

    TA or the Campagnolo Centaur will work.

    You're not likely to find one, because modern cranks are all low profile,
    Your existing spindle is probably 8-12mm too long for a compact double.

    NR used a 114mm non symmetric, Centaur uses a 111mm symmetric, and will
    work with this BB. It'll be about 3mm offset to the right.
