New member, but been lurking for some time. Great site.
I need to replace my original cup and cone BB with a newer unit. I decided to go with a shimano UN55 cartridge unit. My LBS who I've been dealing with for about 40yrs went out of business about 6 months ago and so I've not only lost that but also the valuable advice I could get from the mechanics there. There's another bike shop in the area, relatively new, and the only one for about a 200 mile radius.
My bike requires a 68 X 122 BB, the only one's they stock are 73 X 122. The mechanic there said all I need to do to use the larger BB is install it with a spacer, says they do it all the time. I was worried about the chain line but I bought the unit and installed it and don't seem to have any issues after some minor adjustment of the FD. I'm concerned about there being less of the cartridge actually in the shell. I've gone about 15 miles on a test drive and everything seems fine. Dead of winter here now, -10C today so it may be another month before I can do any serious riding.
My question is , was I given good advice and will I have any issues with this installation down the road?
