I'm new to the site but not new to cycling. I started my serious cycling in my mid 30's and have continued for the past 20+ years. My wife and I train on the tandem 2 to 3 days a week and I do club rides 2 days a week on one of my singles. We participate in one century a year together and I try to fit in two additional on the single each year. Some guys in their late 50's have Harleys or young girlfriends. I prefer our tandems (we have two) and the cellar full of of single bikes that range from steel to carbon fiber. And yes ... my bike shop does love me ...lol.
