Have it measured or ask the manufacturer.

There are only 2 standard shell sizes on your general issue mountain bike. I don't know about freeride and downhill bikes though.

In any case, your bike shop can measure it or you can just go to your manufacturer's website (no I don't mean your mother) and ask them by e-mail.
