Speed Evolution Releases Exciting new Product

speed evolution valves

Speed Evolution is a company created by Bear Valley Bikes owner Derek Hermon to provide innovative products which mechanically advance bike performance. Newly available are the tubeless valve stems. Speed Evolution’s tubeless aluminum presta valve, features a patent pending larger recessed locking O-ring and a larger internal diameter to provide more airflow and less plugging caused by the tubeless sealant. The vulcanized base includes a raised center so that sealant does not seep inside and a vulcanized base that is big enough to 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, and come in cool anodized colors: gold, green, red and pink. They’re a perfect accent to any customized bike. MSRP is $20 a set and new colors and longer length stems will be arriving soon! To buy them or find out more about Speed Evolution visit:
