Your legs say XL but your overall height says L. Some might even say M. For an endurance bike the Venon is long and low. I say, if your arms are proportional to your legs and not your torso, and you're reasonably flexible, and you can get enough rise from the seatpost, get the L. If that is not the case, I'd suggest looking for a bike with more stack and a little less reach, like, say, a Giant Defy in M/L.

Of course, your stem length and rise will depend on your arm length and riding posture. I wouldn't go there without seeing how you sit on the bike.
