While I also don't like the idea of of just 4 sizes of frames....
I just don't see why 650b gets some people all hot under the collar... It's fine if you don't agree with it and don't buy them, there are plenty who do. But, to say it's "haughty" and absurd is to say anyone who bought or has a 650b bike is haughty and absurd....
It amazes me how Grant Peterson can pi$$ so many people off who don't even own his bikes and don't want too.... Of course I can't see what's so special about some bikes to wait five years for one, but I'm not going to rail against them...especially if I've never even rode one. It's hard to make a valid argument if you're just making it on speculation of how the product will perform.
Just another 650b believer...
