Load them up in TopoFusion - if you don't have it yet shame on you. Instead of viewing profiles with elevation, set the vertical axis to grade.<br /><br />Now, as a final consideration, your power will be much reduced at BE altitudes. http://midweekclub.ca/powerFAQ.htm#Q17 says you can expect 75-80% of your sea level power at typical breck altitudes. So if you have a power at threshold of 300W at sea level, at breck it will be more like 225-240. That is a big difference! 2-3 teeth on the rear cog is what that translates into.<br /><br />Here in southern utah at 3k' I'll use a 32.18 or 32.19 a lot. I consider 32.20 - 32.22 as "mountain gears".<br /><br />If you haven't ridden much at altitude before, go conservative!Dave Harrishttps://www.blogger.com/profile/17199180181304602551noreply@blogger.com
