1 Pair of Speed Evolution Valve Stems

Speed Evolution’s tubeless aluminum presta valve features a patent pending larger recessed locking O-ring, a larger internal diameter to provide for more airflow and a less plugging caused by tubeless sealant. The vulcanized base includes a raised center so that the sealant does not seep inside and a vulcanized base that is big enough so seal a Shraeder valve and fits almost all rims perfectly. The valve core is removable to easily inflate and add sealant. Speed evolution valves are made from aluminum, about half the weight of brass.
