What is the inside tube diameter for the bottom cup?

49.61mm. Don't be so concerned with exact numbers. This headset is classified as a standard (external) 1.5" lower cup, and a semi-integrated 1 1/8" upper. The semi-integrated upper headset is a pretty standard size these days which is referred to a 44mm ID standard. There are two routes you can go to find out if this will fit your frame: Contact Canecreek (suggested) or go to their website and use their headset fit calculator. The other option (also recommended) is to contact the manufacture of your frame to find out exactly which aftermarket headsets are applicable. I have this same headset in the "110 series" on two bikes, my Santa Cruz Tallboy carbon and my Lynskey Pro29. This is the most common headset used for tapered headtubes and forks outside of the normal Specialized, Trek, Giant, C'dale, and Niner that all use fully integrated style or semi-integrated top & bottom headsets. They like to make stuff proprietary and confusing. Hope that helps. As for the quality of this headset, I build bikes, and for part selection of a set-and-forget headset that is budget-minded. This is one of the best on the market. The 40-series is considered the "workhorse" of the Cane Creek lineup. Strong enough for downhill but light enough for XC racing and won't break the bank.

its about 3.5 inches... this is not spring loaded. you twist a gear that pushes out the walls of the base to fit the cup

The bottom grid that supports the cup is 2". The cup is very flexible and pliant to conform to the heel and the shoe.

The diameter of the top is 2 inches and the diameter of the bottom is 1.5 inches. The cup is 1.5" tall. The circumference is 6 inches at the top.

this is the one I use and it fits perfectly in the bottom. The filters don't have any measurements on the package because I just looked but, the picture of them on Amazon (see link) say they are 3 1/2 inch. 1 X Melitta - 3.5" Disc Coffee Filter

2 7/8" outside, 2 1/8" inside. Someone else measured the inside as 2 3/16 which may be correct. I'm not that detailed. It fits 2 different coffee makers I have.

Bottom is 3 1/4" diameter x 10" tall. This thermos is so good I'd buy another carry bag if it doesn't fit.Richard

Sorry I didn't see this until today. The smaller part is 1-15/16" the larger end is 2-1/8". Useful for almost any little coffee maker filter.

The inside diameter of the syringe cylinder is approximately 1.25 inches (1 1/4"), The [useless] "tube" is maybe about 3/32 ID (less than 1/8th of an inch)

I read the previous answers and I see why you are still asking this question. We measured with a tape measure to be sure. Top of cup measures 3 1/2 inches. Bottom of cup measures 2 1/2 inches. 2 inches deep. Hope this helps.

It looks to me the bottom inside measurement is a little over 5 1/2". I hope that helps. Robin Riddle

Probably will just measure the bottom of cup. If it doesn't you can always return the item.

Remove drip tray about a 6 inch tall cup will fit. To give you an exact measurement I would have to visit our landfill cause that's where that junk went!!!
