Wanted to say hello and to get some advice from the experts. I am 57 years old and I'm 6'5" 270 with a 34-36 inch inseam. I currently have 2 bikes, a Cannondale M300LE which is about 15 years old and a Miyata road bike from the early 80's that was converted to a hybrid. For some reason, I never warmed up to the Miyata, especially when it was a road bike with the dropped bars and the shifter on the lower frame. I would like to spend about 3-400 on a newer bike and have some questions.
1. Would a decent mountain bike be the way to go given my size and age or should I stick with a road bike? If so, what size should I be looking at? I need something that will be easy on the back as I'm not 18 any more. I will be riding primarily on the roads and on crushed limestone paths.
2. What would be some good bikes in this price range. Will primarily be looking on Craigslist so I will do some research before buying.
3. Any other advice would be very much appreciated. I'm looking to get into shape and my goal is to do a 1/2 century before the end of the summer.
Thanks again for any suggestions.
