Hello,
For a tip that is 5.5, in mm 2.18 by my calculations, would you get a 2.2 or 2.4 mm tube top. I'd be ordering from overseas, so getting both not really an option. Thanks, Craig Re: Ordering a tip top size in mm?

I would order a 5.5 mm tube size, or 2.2 if that is the listing. If too tight you can loosen it a bit by inserting a tapered bodkin into it. But, a 2.4 will not be grossly large. So if concerned about a 2.2, order the 2.4.
Based on my experience, manufacturers are very careful about tiptop bore dimensions and blank tip diameters, and if the blank says 5.5, a 5.5 tube will work. Re: Ordering a tip top size in mm?

Tiptops are generally right on the money. Blanks, which are not precision machined but rely on much hand labor, can easily be off by a half 64th, sometimes more. Get the larger top and shim with a wrap of thread if needed. Or buy both. I doubt shipping would run more for two tops than just one.

Standard conversion for tip top tubes sizes in 64th vs mm:
4/64 = 1.6 mm 4.5/64 = 1.8 mm 5/64 = 2.0 mm 5.5/64 = 2.2 mm 6/64 = 2.4 mm 6.5/64 = 2.6 mm 7/64 = 2.8 mm Norm Re: Ordering a tip top size in mm?

If you're ordering the blank with the tt, ask the supplier to fit it for you. Sorry, only registered users may post in this forum.
