Santa Cruz started the trend towards better valves that stick less and allow more air through when pumping than conventional valves. Now Muc-Off is also blowing through larger valves, offering three of these voluminous air locks in the Big Bore series. The Lite, Hybrid and Ludicrous are alternatives to Presta and Schrader valves and, according to Muc-Off, allow more than twice as much air through as their conventional counterparts.
