    Changing Drop Out Spacing

    I''ve got several 10 speed bikes with 120mm rear drop out spacing. Is is possible to spread the rear triangle to 135mm?

    That's a lot of difference. You're going to stress the welds at the brake and chainstay bridges. The tubes will get bent enough to notice at those points too.

    On the other hand, what's the value of an old steel roadbike frame with 120mm spacing? It doesn't look to me like you've got much to lose. I say go for it.

    Why not go to 130mm, the current road standard?
