Evening, decided its time to change my rim for something lighter/doesnt give me a pinch flat every ride. ive tried 10 psi, 15psi, 20psi, 25psi,30psi &35psi. all of which give my a pinch flat. pretty sure its the rim as ive tried numerous tyre/tube combos. so basically what stock rims are anygood? quite like the look of the atomz one and its pretty light too. what holds a grind best and is relatively light/strong?? cheers
