In answering the question above, I am willing to allow test rides on a case by case basis. I love CB. It has kept me riding. I had a high dollar Cervelo, which I loved, but was unable to ride due to physical pain. CB saved my cycling life. I have ridden my S40 multiple times in the local MS150 ride from Houston-LaGrange-College Station and have done so in complete comfort even though the route is quite hilly. I currently do most of my riding indoors due to a significant rise in automobile traffic in my area. That said, I am very active on Zwift, riding my S40 daily and even racing on Tuesdays (ZRL with the Crusin Cayuse) and Thursdays (WTRL with the Herd Coyotes/Road Runners).
