Sweet thanks! Dlnoss your the man! If slc is at 4300 elevation, that means I probably ride around 3500 elevation when I go to the dunes here in utah. I guess I will stick with the 19cc. What are the chances of my crank going bad if I run the 18cc's? And also, one more question for dlnoss- How does the bansheehq discount work when I pay?
