Hello everyone, ran across this forum while doing some research on frames as I am in the process of switching from an old Trek 820 Mountain Bike to a road bike. I bought the old Trek about 15 years ago road it some and then hung it in the garage until last June 13th at which I pulled down and started riding again. With my weight and hills around my house I had all I could do to ride more than a mile. Today I am riding an average of at least 15 miles per trip and my longest single trip is 71 miles. Yes I have lost a lot of weight 70 lbs and want to lose another 25 or 30. Winter is coming up and I am looking for alternative exercise routines. Would like a rowing machine but are expensive and used ones don't show up much. I will more than likely spend a lot of time in the over 50 forum as I am in my early 50's. Looking forward to getting to know a few people here.
