Thanks everyone for all the encouragement! I go between being excited and terrified, LOL re: clipless pedals. Since I hadn't used either system, I thought the SRAM might be better for my grip as I age. I've been on a bike tour almost every year since 1988, but circumstances are preventing me this year. Hence, learning to use the road bike this year, in preparation for the next one, hopefully 2014 since I turn 70 in January. Since there is a rail trail on the Cape, and bike lanes along the Charles River in Boston, I have safe places for my first attempts. Hills are the big worry! I'm very determined and adventurous so I know I will be fine! Thanks again...will keep you posted!
