I am going to patent Fully Adjustable Rim Technology right now. F.A.R.T. So you can adjust your rim size, cs length and fork lowers on the fly. K, you heard it here first.
This "debate" is just a tall guy argumentation. OK, you're over 6", you're skinny, you look ugly on a 26" bike... OK, go find yourself some bigger wheels, but just let normal people live their life and buy wheels suited to them and have fun. There's no fun with 650b or 29" wheels on a bike for people under 5'6 (that's at least 3/4 of the people in this world). Just to go a bit further, there's some frame sizes going from XS to XL, wheels should fit frame size, period.
