Just curious what size tires are you using with your 700cc kit. I have a track rear wheel that I wanted to use. I wanted to know what width was the tires you were using. I've read somewhere you shouldn't use tires more than double of your rim's width without the tires install. I measure my rear wheel and it was about 24mm width, so that would mean that I can use any 700cc tires that is less that 48mm is width. Is that true? Thanks in advance again.
