Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

Question about tubes and maybe tires too...

To start off I'm new to the whole bike thing, I've ridden bikes before but never cared as much as I do now, and since I started to care I realized that I should learn as much as possible, but that stuff doesn't really matter.
So I was looking through City Grounds and was planning on getting replacement tires and maybe a new wheel if I ever need it. Firstly I understand tire sizes but what confused me was that when I was looking at the tubes they had another measurement. Example, I choose the 700X2325 tubes and in the drop down box above it, it asked 32mm, 48mm, and 60mm. Now I've messaged City Grounds and didn't get an answer back so I thought I should ask here.

City Grounds | Q-Tubes 700c Presta Valve

The box that is marked color has those three numbers I've stated previously. Any help would be helpful to me in my confused state. Oh, and since you've decided to help maybe you can answer this question for me also... Can you mount 25c tires on Aerospoke 700c wheels? I feel like it's a yes but I'm new to this and would rather hear someone with more experience say it.

Those numbers in the drop down box is how long the Valve is. Measure your rims and get a rough estimate on how thick they are and pick accordingly. I would say you could mount up to a 28c tire on an Aerospoke no problem.

The first number is the wheel size (700c) and the recommended tire width that it will fit (23mm to 25mm). The second numbers are the choices in valve length, and you will need either a 48mm or 60mm valve with an Aerospoke, which can easily accept a 25mm wide tire.
