Got an old bike that I restored some time ago, and the original tubes literately burst on me today (I knew I should have replaced them long ago, they are probably 10 years old) and now I have some questions on replacing them.
Looking at the available tubes, I see most of them have presta valves. The originals and my current replacements are Schrader. I don't have much preference on valve, I just want to know if I should limit my selection.
The real question is, I really never paid any attention to the holes drilled in the rims. Do they have different diameters for each type? Would a larger Schrader hole damage a presta valve tube? Or are the rims pretty much universal?
If this is useful, the rims i'm buying new tubes for are: an old MTB Araya RM-20 and an unmarked original from a cheap fuji-4.0 700 bike
