Rollin' again after an auto accident 2 years ago [while in my car], which has left me with increased arthritic pain. Slowly increasing cycling distance every 6 months. Have had to make some changes to my bikes. Riding all I can for as long as I can. I like double or triple-butted chromoly steel bikes, which absorb more road vibration, and 700 x 28c to 35c tires - depending on where i ride. I'm not fast but I'm having fun.
