I am an old timer, using Fat Billy’s reasoning. I am a Shimano fan normally, but just bought my first bike using SRAM components and liking them so far. Still a fan of the rapidfire trigger system but getting used to the SRAM setup didn’t take long, as it is pretty intuitive. I am interested in switching this bike to a 2×10 setup after this season so I will watch this discussion and others like it with great interest!
