Hi , I have an old 1984 SANNINO italian road bike and i'm gonna FIX em' up.
I just don't know what crank and BB spindle length to buy...
I have 126 mm spacing on the rear and got wheels with spaced formula hub 126 mm.
my BB shel is like most Italian - 70 mm. what BB spindle length do i need to get normal chainline and what track cranck set will fit there?
You may have better luck in the SingleSpeed/FixedGear Sub-forum. This sub-forum is mainly for track only bikes, not conversions.
With that said, good luck on your conversion. Ive found that any older conversion usually is more headaches than its worth unless you have a SS/FG savy friend with surplus parts and free time to help out.
