He he. First ride today. There's a combination of things that might make this my favourite bike and 650b's are one of them.
I have gravel kings in 700x32mm and 27.5x1.75". These ones have a slick middle strip with light tread on the shoulders whereas the 700's have two slick shoulders with tread in the middle (which makes no sense to me). Having tried Tarmac, dirt, gravel, trail and cobbles I really rate these gravel kings.
