Caffelatex Tubeless Valve - Pair

Caffelatex Tubeless Valves bear more than a passing resemblance to our favorite tubeless valve ever, the Mavic UST valve. What makes the Caffelatex valves so great is the shape of the rubber base that sits inside the rim. First, it will sit all the way down into the center well inside a UST rim, a requisite for proper sealing. Second, the rubber base also seats perfectly in regular tube-type rims, and whether or not the valve stem hole is drilled oversize on the interior wall to accommodate a tube, it won't pull through when you're in a hurry to pump it up. It's got a removable presta core to facilitate easy sealant injection. They come in a pair and include lock nuts and a valve core tool.
