i just got an unmarked old italian road frame that for some odd reason, came to me with a spacing of 110mm.
i have no clue why it would be at this spacing, when one would assume it to be 120 or 126.
anyways, i am trying to cold-set it to 120, using sheldon browns method, but with no luck. when i push on the board where it crosses on top of the seat tube, i feel it flex, then i stop and measure the stays, and nothing has changed. it seems like the flex is happening in the main triangle, which i definatly dont want.
honestly i'm a little scared to apply alot of force, but is that what i have to do? does the fact that its fully chromed have anything to do with it? (i dunno... mabey makes it stiffer?

)
it just aint working for me. any help/opinions would be awesome.
