This is a friend's bike:
Frame's about 20 years old but parts are modern. Think it may have had stays respaced for modern 10/11-spd(?). Drop out looks bent in from stay - does that look healthy in photos? Note the horizontal line where drop-out joins stay.
Seems to run ok spinning through all the gears on the work-stand but not so good under weight/strain of proper riding.
Says gears feel as though they're stuttering & wheel feels like it wants to come out.http://m.flickr.com/#/photos/106794103@N04/10514122463/
Ps. Will be next weekend at least before I actually get to see bike...
