The most important suggestion for a 50+ returning biker is.................

You are unique. A lot of what you will hear in the LBS (local bike shop) and on many forums applies to 14-30 year old cyclists. There are buckets of what to buy....how to fit...where to ride...information that may or May Not be appropriate to your situation. Ultimately you will have to make up your mind what fits...what works. Do some research. Ask lots of questions. This forum (50+) is full of some common sense information (and other stuff) about what works for us.

Whatever you do...........get out and ride. Go on, give it a try. Its as good as walking (better) and you will get to see a lot more of the world in the process.
