I have been thinking about what I'll be riding in my 70's (now 65). Right now it is a Specialize Allez A1 Sport. As the reflexes, etc., slow, should I consider a touring bike, which would be less twitchy? Should I go for a recumbent, which would decrease the falling distance? I'd especially like to hear from those who have gone through this stage of cycling. If there are any who have quit, but still follow this forum, I would like to hear from you too.
