Charge Plug

Sorry to bump an old topic but I figured it's better than me making a new one.

I'm looking into purchasing the 2010 Charge Plug. I'm 5'10" and have an inseam of 34"

What frame size would best suit me? I'm leaning towards the 56cm but am not sure if that will be too small etc.

no one can tell you that, go to your local charge stockists and ride it. there is bound to be an evans near you, just give them your credit card and off you go.
