BB Spindle Length Differ From Suggested
I am currently in the process of rebuilding a 72 Peugeot UE-8 and will soon be purchasing a new BB to go with a set of mid-80s Specialized Touring Triple Cranks I pulled off my 1984 Davidson Tandem. According to the Specialized Catalog, the suggested spindle length is 114.5mm for a 68mm BB. The closest spindle lengths available for the BB I plan to purchase are 113mm and 116mm, so we're only talking a difference of +/-1.5mm.
is there any real consequence of going short or long on the spindle length when the difference is only 1.5mm as in this case and what are the real effects for each scenario?
