If you get a Phil BB, not only is it adjusted somewhat with the Lock rings, as neither shoulder
against the frame BB shell face.
But it, also, can be pressed sideways through the bearings ,
as the axles have no interior shoulders,
and rely on the precise matching of the bearing ID and the spindle OD.
by that fact you can change the offset ... I have done so, myself,
nothing more than the 2 mounting tools, a flat washer, [span the opening on the tool],
and the bolt that holds the crankarm on as a press.
an adjustable wrench to hold the square , and a crank bolt wrench to turn the bolt.
bolt pulls the spindle through the bearings.
Surely Omaha Has a Bike Shop to go to to get you the right parts..
If not Lincoln would, colleges have more bike Use.
Campag 68SS120 is 112 long, [ for 5 speeds] in the catalog #17
track is shorter, triple and Cross use a longer one.
... there is also the specifics of which one, as there are 2 cup types
and a co-reponding axle for each .. thicker cup has rifling spirals
to expel grit without a contact seal . bearing races in the axle are thus closer together.
bring what you have to the Bike shop and they will call Up Phil and Co.
or get thru one of the distributors they do business with.
problem solved. top shelf .
