I'm looking at the Tallboy frames and want to know sizing for the frames. I have ridden Niner Xl size frames for two years. Trying to pick between a Xl and xxl size. I'm 6' 3" and want a longer head tube than the Xl so looking at the xxl. Maybe to long of a top tube. Thanks for any help as I can't ride either of the frames. I do own one of the first year Blur's and have had a Superlight and Heckler, I just like SC bikes.
