Anyway, I like to run wide 26" tires, 2.25" to 2.35". On a conversion, you'll have to run narrower 650B/27.5 tires. That alone is a dealbreaker for me. But, yes, a 2.0" 650B tire should clear many 26" bikes except for XC race bikes that can't even fit a wide 26" tire.

Thanks for the input. Yeah I'm concerned about the width of the tire too. I'm running 2.3 on the front and 2.1 on the rear of the green bike. However, the hardtail has tubless 2.1's on both. Granted, I only use it for milder trails.
