Thanks everyone for the advise. Denver Fox, I work midnights at the Post Office and have a difficult time getting weekends off. After I posted this cry for help, I went on a training ride in upper Michigan. (I took a vacation day and added it to my non-scheduled days) I rode 80 miles today and drove home for 260 miles. It is 9:44 pm and I have to get ready for work. I will write back again. I ordered the 28 chain ring and the mountain gearing and a new chain. I rode 160 miles the last 3 days in large hills. I've lost 30 pounds since last year and the hills were a breeze. Thank you everyone.

p.s. I was on my way to lower Ohio and W. Virginia with my 63 year old coach. He lost his $3500 Serotta off the back of his car. (My bike was inside the car.)No one beeped and we didn't see it disappear. The Michigan and Ohio State Police have the report. So I drove up north by myself.
