Seatpost clearance tolerance?
Making a custom seatpost shim for my litespeed. Trying to figure what the normal, reasonable, useful (pick your word) tolerance is for a seatpost. ID of the shim is easy- I've found that to be true to the billing, posts tend to be undersized. I can also bring a seatpost to work with me much easier than a bike with no seat.
I know for sweat or welded pipe fittings, it's .007" (ID of female fitting > OD of male of fitting) which is about .178mm. Is this about right?
Hell, anyone know the ID of a 1 1/4 straight wall Titanium tube from the early 90s? Hell, even an idea of the common wall thicknesses? The best I can surmise with my questionably accurate calipers, the wall thickness is 1.05mm
