I recently replace my beloved 2010 Trek 520, with 46,000 miles on it, with a CO-OP ADV 1.1, which I hope to continue to tour with. I only have about 1000 miles on it now, but I REALLY like it. It's a bicycle designed and built with touring in mind. Best value I could find after quite a bit of research. Hope your son enjoys his.
Thanks I think he will when grows a touch more. The reach is pretty far and we did a ride or tow that his back was kinda hurting after a while.
