    Hello,

    Here's a puzzle(r) for you. My 2002 Chorus 10v normal cage r/d has a 56 mm distance on center
    between pulleys. My 2001 Daytona 10v r/d (only made with a medium cage) has a 56 mm distance on
    center between pulleys. The Daytona was supposed to be 29T rear cog compatible; I'm ready to schlepp
    my 2-year old around.

    It seems that my Daytona r/d isn't for a 29T max cog and supposedly was never made. Any ideas?
    Thanks in advance for your response.

    Not sure where you're going with that "never made", but, for a 29t cog, the Daytona and Centaur also
    exist in a "triple" version with 79mm between pulleys. There isn't a "Chorus" like that because it's
    labelled a "Racing Triple" instead.

    The 2002 Record and now 2003 Centaur made for 3x10 have longer cages than what was available before.
    It works perfectly on my tandem which is 52/42/30 x 13/32 and is beyone the derailleur capacity. I
    hardly had to move the derailleur away from cogs. With my Veloce triple, which I used for several
    years, I barely made it with the B screw all the way in.

    My 2002 Medium cage 10s Chorus has the same distance between pulleys as my Veloce 9sp triple, which
    is the same as what the Racing-T and Daytona long cage was and Centaur standard is. And they wonder
    why I no longer know what medium, long, and regular mean and thatwrenching Campy is voodoo.

    Someone has to inform my pre 2001 shifters that they cannot use new derailleurs. Also let my 2002
    shifters know that they don't work with older derailleurs.

    I always thought the Racing-T stuff was Athena quality.

    Put the Daytona on the 29t and go ride-'max' teeth info from manufacturers sometimes means upgrade'.
    Altho Daytona had two cage lengths, they always had a 13-29 10s cogset...so just use either rder-

    Hey, readers. What books do you like for detailed repair and maintenance instructions?

    By detailed I mean how to take a bike apart to the bearings and bolts. How to reassemble is
    a plus :)

    My 1981 copy of Eugene Sloane's "Bicycle Maintenance Manual" is wonderful, but is missing a few
    recent developments. 21-speeds were exotic and there were no cassette hubs.

    I have 'Zinn and the art of road bike maintenance' and it has proved to be useful. Park tools
    website http://www.parktool.com/repair_help/index.shtml section on maintenance is good as well.

    Except for wheel trueing or building, I do all my own maintenance including stripping and rebuilding
    and predominantly use the following four reference sources.

    Hardcopy/Softcopy resources
    # Barnett's Manual - super comprehensive. Most of previous edition
    downloadable FOC in .PDF format online.
    # Zinn's "Art of ***bike Maintenance" books - More general and an
    easier read, but very practical. As another poster has said, there's a fair bit of overlap between
    the RB and MTB volumes, although nothing which a healthy dose of hands on common sense and item
    specific research won't alleviate. Worth the $$$.

    Online resources
    # Park Tool's website - superb & FOC Sheldon Brown's website - likewise & FOC
