      Just make sure your bike can keep up.Sure you’ve got moves and sick skills. But you need a bike that’ll showcase them? Take a hint from Dave Dillewaard who hits it all - from street to park, Dew Tour to X-Games - on his GT. We’ll give you all the performance we give him: micro-sized gearing, a mid-sized bottom bracket, bombproof build. You’ll be shredding like Dave in no time. Yeah, right.
