WTB Horizons no good? (oh, they were 47mm so might not fit depending on your frame)
WTB did a ThickSlick in 650b

Most of them are at 47mm. But going wider was kind of the point of 650b
Yeah 42 is the biggest it will fit. Everything is 47+ now. Real bummer, I want to be comfy but I also want to be a lil fast. I'm worried going narrower will have the frame sit too low (it's a conversion).
GK Slick 27.5x1.5" (38mm) or 1.75" (44mm)
