You will be quite pleased with that set up for chain and sprockets. Great choice, it's the same package that Rocky Mountain ATC Cycle sells for about the same money, same set, same $. Been there, done that, but I went 15 tooth again last time. I do want to give the "16" a go next time myself. Oh, take care and have some PATIENCE when it comes to compressing the parts and bits of the chain master-link gizmo. A bit of confusion may set in, but use your head, let us know what you think of the new gearing, would you please? Or shoot me a PM sir. I want to know..
