I saw a road bike today at a shop in Houston that had 11 gears on the back axle and two in the front. Mine has ten in the back and two up front. every year I get into a situation going up a hill where I wish I had one more gear. Are 11 gears something new? Is that eleventh gear for climbing or for speed on the high end? I ask the fellow at the shop but he danced around the subject until another customer came in and he walked away from me to help the other person.
