Our bikes are big, just look at those reach numbers! So when picking your sizing take this into account. Here's a couple of examples,

  • If you usually ride a medium and want a longer feeling bike, stick to a medium with us.
  • For those out there between sizing on this chart, what sort of feel do you want? If you want snappy and playful, go for the size down and get loose, or if you want long and stable, go for the size up and hit those trails like a south bound freight train!

We recommend you go and check out the bikes with one of our dealers to make sure you get the size right for you! Find dealers here.
