    Rear spacing ?

    I'm a bit ticked right now...

    Just acquired a 2004 Giant TCR frame off ebay.
    http://www.bikepedia.com/QuickBike/B...=TCR&Type=bike

    Out in the garage working on it when I discovered the rear spacing is ~ 113 mm.
    I cannot see any sign of damage on the frame, it was shipped UPS and box / packaging showed not signs of damage.

    Each chain / seat stay seems to be at equal distance from the centerline and show no signs of damage.
    I've e-mailed the seller inquiring.
    It is correct that you DO NOT want to try to alter the spacing of an aluminum frame - correct?

    Did you try fitting a wheel in the frame?

    113 cm = 44.49 inches.
    Did you mean 113 mm?

    Thanks - already jumped on Sheldon's site to double check the measurement to make sure I wasn't dreaming...
    Unfortunately I'm certain of the measurement.
    I'll wait a day or two for a response from the seller and then file a grievance thru ebay and paypal. Still steaming right now...
    Take Care,

    If that's truly the correct measurement, something is really wrong. It should be spaced much wider since it originally came with a 9-speed rear according to your link.

    Try putting a wheel in there first.

    First thing I did was try to install my old rear wheel; not even close.
    Like you said it; it is WAY off. Have the frame in my stand and looking down the top tube and thru / pass the seat stays all looks symmetrical - it's as if someone deliberately altered the spacing; but the only thing close to a 113 is an old 3-4 speed - unless they were trying to make it a track frame or fixed gear. What are they? 110?

    My SS is 120mm. Older coaster-brake hubs were 110mm, but I can't see someone trying to put a coaster brake on a frame like that (Except I did, long ago. Long story.) I bet the frame was squashed at some point and the seller is trying to pawn it off as undamaged. I hope you get your money back.

    EDIT
    113 cm = 44.49 inches.
    Did you mean 113 mm?
    Doh - yes, sorry for the typo. Fixed in OP.
    Even though I feel like a clown it's not a clown bike = however, might as well be.
    Last night I went ahead and 'forced' the rear wheel in - took quite a bit of pressure; only about a millimeter or two off-center.
    I'll wait for a response from the seller and if not acceptable I'll file a grievance through the Ebay Buyer Protection service.
    Take Care,
    Steve

    Take the bike to your local LBS. Have them use the ***(f.a.g) tool to check the allignment. Easy peasy.

    I'll do that; I like the frame / fork and would love for this to work.
    How concerned should I be about aluminum stress fractures or fatigue?
    I can't see any signs of anything and obviously a second set of eyes at the LBS won't hurt.
    Take Care,
    Steve
