  1. My 10 year old Colnago is now becoming my rain and commuting bike, but
    it needs work. The rear wheel is shot--just doesn't stay true, and my
    left 8-speed Ultegra STI shifter is toast. I want to get this bike back
    on the road as economically as possible, but if I can swing it, upgrade
    to 10 speed since I have a spare set of Mavic wheels that are 10 speed.
    My question is this: Can I just replace the broken STI shifters with a
    10speed version or do I need new front and rear derailleurs too? Also,
    will my 10 year old Ultegra cranks work? Someone told me I had to
    upgrade that as well. (No !!!!) Finally, will a 10 speed wheel fit the
    frame of a 1996 Colnago? Did drop out width get bigger since the advent
    of 10 speed or am I OK. I know that's a lot to choke down! Thanks for
    any or all answers...

    Most "economical" way possible - stay 8 speed. If the RIGHT side STI shifter
    still works, why not replace the broken left STI with a downtube shifter,
    fix your rear wheel and RIDE! Remember, your left 8 speed STI shifter
    controls the FRONT chainrings. Thus, you could "be like Lance" and use a
    downtube in its place. With a downtube shifter, not only would will you save
    money, you'll save weight too!

    Just the shifters, as long s the 8s Ultegra is not worn out, it will
    work fine with 10s STI. Crank is fine w/o any changes. 10s is the same
    rear spacing as 8s and 9s....BUT I hear the Colnago crying from
    here...get some Campag ERGO, RD, all else is fine, a shimano 9s cogset
    and chain, go ride OR, new Campag rear wheel, 10s cogset and chain...

  4. Any left shifter will work fine, doesn't have to be 8sp. I found a new left
    hand RX100 shifter on Ebay for £25.......Cranks will be fine. I run a mix of
    7, 8, 9sp, Shimano bits without any problems.

    Sounds like the rear wheel is not properly tensioned.
    * Put a drop of oil or penetraing lubriant on each
    nipple. Preferably from the inside after removing the
    tire an rim tape. Let it penetrate for twenty-four
    hours.

    * Slack off most of the spoke tension and inspect the
    rim for flat spots and bends. It could still be bent
    into shape, or you can find a new rim with the same ERD
    and reuse the spokes.

    * Now bring the spokes back up to high tension while
    keeping the rim true.

    * Stress relieve the spokes.

    I did not put in much detail. There are resouces for
    this work.
