I am considering going tubeless on my Felt Z3. I use this bike primarily for long rides (4 hours or more) and I'm starting to tire (pun intended) from multiple flats on rides (happened to me recently). Most of my flats have either been pinch flats or small pieces of glass or metal-going tubeless could remedy that. I'm thinking about going the Stan's No Tubes route. They seem light and have great reviews....anyone have any thoughts?
