I'm a bit of nob when it comes to knowing basics about mountain bikes. However, I was wondering how can I can find about what suitable size tubing will suit my bike?
Look on the side of the tyre..it will say eg..26x2.1, 26 is the tyre diameter and 2.1 is the tyre width...an inner tube do widths from 1.75 - 2.125 so they fit pretty much most common tyre sizes.
