My rims came as presta rims, but i had the LBS drill them out so i could use any type of tube if i need too. 99% of the time, i use a standard presta tube with a shrader to presta adapter on the rim.
I use presta for a few reasons, thet tube will not turn in the tire, as the valve is bolted through the valve hole. The valve is not spring loaded, to deflate you just need to overcome the air presure inside the tube, you can get a lighter presta tube then a schrader tube. The nice thing about schrader tubes, is you can get them anywhere, you can get air at gas stations, price is usualy a bit cheaper then presta.
Im not sure if presta tubes can hold a higher PSI, anyone else know?
