I love it! My SS is a rigid 29er (Salsa El Mariachi). I went with a 29er because I could get higher volume tires for it and because my local trails are well suited to a 29er. I went rigid because it was a good way to save money initially, and now I enjoy the simiplicity of it. No messing with a suspension fork.

My El Mar is definitely lighter than my geared full-suspension, but it's like comparing apples to oranges there.

I do it because I enjoy the simplicity of it, the leg-burning, lung-busting workout, and the quietness of riding a gearless bike. It has definitely made me a stronger, smarter rider. I use my momentum more effectively, pick smarter lines, and push myself beyond what I think I'm capable of.
