|   Presta vs. Schrader Valve? | smotley
Mar 28, 2003 7:38 AM | | I have a road bike (with Presta valve tubes) and a mountain bike (with Schrader valve tubes). I now have two flats on my mountain bike and am looking to buy some new tubes. Which type of valve is better and why?
Thanks in advance. |

I myself like Presta valves better for ease of use... |

Mar 28, 2003 8:12 AM | | The narrow valve used on most high-performance bicycles, and all tubulars. Also known as a "French valve". The wider Schrader (automotive style) valve is used on children's bicycles and utility bicycles.
Presta valves have built-in valve caps, which must be opened before you can pump them up. These caps are "captive" nuts, which cannot be removed. Since there is no spring in a Presta valve, this knurled nut must be retightened after inflating the tire, or the valve may leak slowly.
Presta valves are light, and don't require as large a hole in the rim. Since the don't use a spring, they can be easier to pump with a hand pump.
Separate valve caps are not needed with Presta valves. Valve caps, lock rings and Schrader adaptors can actually be dangerous, if you ride tubular tires. |
