I'm finishing my 2016 Kona Major Jake build. I've got wheels which are an internal width of 20mm. I bought some Donnelly Xplor MSO 700x40 tires for it. I mounted the rear temporarily just to make sure I have clearance everywhere.
The only place where it looks tight is on the crank side of the chainstay. There is about 5mm of spacing between the tire and the frame. Planning on running these tubeless for mixed asphalt/gravel rides so probably will be running them in the mid/low 30 PSI range.
Still on the fence about fenders...but just looking at it without fenders, is this going to be enough room?
