Alex CXD6 Wheelset Clincher or tubular? The 2015 Kona Jake the Snakee has Alex CXD6 wheelset installed, but i could not find any information is it for tubular, clincher or for both tire types ? 

It has Challenge Grifo Comp 700x32c tires but apparently there are both tubular and clincher version of those available too.
That wheelset includes clincher-style rims that are tubeless compatible. 

Be sure not to confuse tubular with tubeless. Tubeless looks similar to a clincher (beads on each side, open on the bottom), but doesn't use an inner tube, while tubular is a single whole tube with tire and inner tube combined; these tubular need to be glued on the rim.
