It came with the Dura Ace 7800 crank, I am wondering if I should get a compact crank set. My stock one is 12-27 and 53-39. I am traveling at the edge of my ability but feel I can get the strength needed during the year. I have tried Lookout without too much trouble with a gear or two to spare at times; however, want to go do Mt. Evans. Any suggs, or can someone comment on the difficulty using this set up?
