> 3 dayHands down, the worst bicycle related purchase Ive ever wasted money on. These valves are garbage! They clog if you look at them sideway and are completely overpriced. Spend half the money on Stans, WTB or some other reputable manufacturer on a better quality set of valves and ride with confidence that they wont leave you stuck on the side of the road trying to clear a clog so you can pump up your tire.
