I have Gios Evolution all-steel frame with the fixed steel
horizontal dropouts. It has never been built up, and with
too many bikes I sold it to a fellow who would build it
and ride it.
When he came to pick it up and put it on a roof mounted bike
carrier, the rear wheel on the drive side would not go in,
but the non-drive side would. After looking at it, it was
evident the rear right dropout was just a bit smaller than
other at the front end of the dropout.
I took a open-end wrench, put the handle between the
dropout, and with one application of force on the wrench
the dropout now accepts the rear wheel with no problem. It
also looks to be the same distance the length of both
dropouts now.
My questions are:
(1) What is the possibility this adjustment will weaken the
chromed dropout and cause problems down the road with
this drive dropout from the small (maybe 1mm)
adjustment?
(2) Is this something that others have experienced maybe by
the dropout closing a bit when shipped or something?
(3) Is there a better way to fix a problem like this in the
future should it occur again?
Thanks,
Frank
