Cilo Bicycle Upgrade

    I have a late 80's (1987?) Cilo road bike. It has a shimano biopace dual
    crank and 6spd cassette. I like the bike and would like to upgrade it to be
    a triple crank (for hills) and 9 spd cassette. I was thinking of Shimano
    105 components. Is this practical / doable?

    Any comments / suggestions would be greatly appreciated.

    This bike is most likely spaced for a 126 mm rear hub. If it's one of
    the steel Cilos, re-spacing it is a trivial matter, and it's well worth
    the upgrade.

    See: http://sheldonbrown.com/frame-spacing

    If it's one of the glued aluminum (Vitus) ones I'd be nervous about
    spreading the frame.

    You might want to read a recent thread here on compact cranks (ie cranks using
    smaller chain rings). These permit one to easily achieve the lower gear ratios
    found on most triple cranks without all the fuss and expense. Useful with any
    number of cogs in the back.

    Yes it is doable. It will take some work. You will need to have the spacing
    on your rear triangle re-set to 130 to accept a 9spd wheel. You will need to
    buy:

    rear wheel
    9spd cassette
    9spd chain
    9spd cranks
    matching BB
    That is a minimum. If you want to go to STI, then you will also need the STI
    levers and an index compatible derailleur. Check the prices on these parts and
    then you can decide if it is worth it to you.

    Maybe new cranks, BB and front der are not needed?

    For conversion to 9-speed, they're not needed, but the original poster
    also mentioned that he wanted to upgrade to a triple in front.

    The O.P. could save a lot of money by going to a wide range cassette and
    leaving the cranks alone. This would require a new rear derailer, but
    derailers are cheap. He could get much lower gearing than he or she has
    now without changing the cranks. Going from a 42 to a 38 tooth small
    chainring would also help, again at a much lower cost than going for a
    triple.

    That would be true, except the OP said he wants to switch from a double
    to triple crankset.

    Sorry, you (and Sheldon) are right... I should read more carefully!

    My thanks to all of you. I had said that I was looking to go to a triple
    crank, but the responses I've received will make me think about that.
    Options have been brought up that have me thinking that for a start, I may
    just go to the 9spd and perhaps a triple crank later.

    Thanks again to all.

    Have a good bike shop cold set the rear triangle to 130mm. Shift
    levers, crank, BB, front and rear ders, cogset and chain. Easy and
    doeable. Also look at Campagnolo Veloce, probably cheaper and more
    durable.
