Hello everyone! I have posted my returning details in the over 50 forum. I am happy to find this forum, as I am just getting started on my way back to fitness after a long layoff for no good reason. I ride a Schwinn criss cross I modified years ago to take some off road abuse and climb trails in New York. Currently it is in a non-aggressive road tread configuration acting as my "fitness bike"...I also have a Cilo 12 speed with shimano 105 (remember that?) and sealed bearing hubs...tange #1 double butted tubing throughout (remember that?). My goal is to be back on that in my samson clipless pedals (the very first version..remember those?) by summers end. Wish me luck!
