wackwack Posted June 9, 2009 Posted June 9, 2009 Are there any real benefits of using presta over schrader valves? I'm really thinking about drilling my rims to take a Schrader valve... What think y'all?
dirtrider Posted June 9, 2009 Posted June 9, 2009 The one got a nice nut to keep the tube in place . maybe not that important !
wackwack Posted June 9, 2009 Author Posted June 9, 2009 wackwack?why? It may seem dof but..... 1) with a toobless conversion it is so easier to get 20'' tubes2) i have been caught out twice when losing tyre pressure while out on a ride i couldn't pump my tyre at the filling station3) then my bike & the mrs bike is the same - i don't have to turn the jobbie on the floor pump. Are they lame excuses??
Red Zone Posted June 9, 2009 Posted June 9, 2009 I think that presta valves are used because they are thinner and require a smaller hole in the rim, which is therefore stronger. Probably not so important on wider MTB rims but as a rim gets narrower a schrader valve hole probably compromises the structural integrity of the rim

Pappa Bear Posted June 9, 2009 Posted June 9, 2009 .....dont drill your rims It has been designed with a certain dia hole.... not a bigger one...... Will you drill your frame? If your answer yes - drill your rims. If the answer is Na - don't drill your rims.

Some for shraeder valves and some for presta? I do not think so. And yes, I have drilled my frame so that the water can get out.
