ok, my buddy is 6'3" and around 230lbs...He is now concerned about the frame not being strong enough..
He thinks it may begin to flex and possibly form hairline cracks from heavy track riding.
He is a fairly fast rider and is worried the forces of doubles and triples will have a negative affect on the frame lasting. He intended to keep the bike for several years and is worried about it lasting and staying in good shape for that long..
Tell him to stop being a such wus and go ride the shit outa that thing...It appears more mechanically sound than most of the bikes my friends ride...Anything his spine can handle, that frame can handle...
