These rims are for a Ragley Blue pig. I'm looking at Spanks. One is 30mm inner and the other is 35mm inner. I want to run 2.3 to 2.6, mainly for XC stuff. Supposedly this frame can handle up to a 2.8 which I can't say I'd use, but who knows. I might try it and like it. The build is mainly for where my Spartan is overkill. Picture imba trails. My only concern about the wide rims is that with a 2.3 tire, it's kinda taking away what little suspension I'd have. Let's hear it.
