Singlespeed bottom bracket question...
Hi all,
I've recently picked up a nice lugged steel frame to build up as a SS cheap knock-about bike (well that was the intention...) anyhoo - i'm using an old bontrager road crankset which was on my commuting bike on a 72 x 110.5mm IS bottom bracket, however the new frame has a 70mm Italian BB - is it just a matter of getting an Italian 110.5mm (ish) BB or am I missing anything else? The rear spacing is 130mm so i'm using spacers on a standard freewheel, so should be able to jig the spacers around to get the chainline right.
Cheers,
J

Yes, make sure the bb matches the splines of your cranks...or tapersleft the forum March 20230

Cool, was hoping there wouldn't be any underlying issues i'd overlooked - not sure if the frame was originally 130mm or if it's been re-set from 126mm but the standard wheel sits perfectly straight in the dropouts & the crank is a modern road double so has std square taper axle fit - looks like a std Italian square taper BB should go right in (famous last words)
