Jumping on the Prevelo was a noticeable change in how he rode. I immediately noticed his feet were on the pedals correctly. Stopping wasn’t such a chore as he could reach the levers without removing all four fingers from the bars. Shifting was easier, too. The grip shift on his old bike had him moving his hand so much that he had to take his concentration from the trail and focus it on the shifting task. Plus, the grip itself was coming off the bars the more and more he shifted. With a standard thumb shifter, shifting wasn’t only easier, he learned to do it without looking.
