This just in: from the National Institute for Radness. Your bike will shred, send, huck, plane, stick it, bomb, carve, rail, rip, and shred 13.6% more if you put anodized valve caps on your valve stems. Be the envy of all of the suddenly less gnar kids. Make waves at the Rotary Club. Cause riots at bingo night. These valve caps are SIIIICK.
