I've searched the forums and googled for the correct sizing of a bottom bracket for above mentioned road bike. The threads on the chain side have worn lose and I need to replace it ASAP.
I've also looked at the spec sheet from the 1986 magazine (http://bikecatalogs.org/SCHWINN/1986...1986Ltwt30.JPG
but was unable to find any helpful information.
Thanks in advance for all the help I can provide pictures or anything if necessary.
