i don't know if i spelled that right but what are your thoughts on drilling out a rim to accept a schrader valve stem?

the rim is plenty wide so that isn't an issue.

love to hear your thoughts on it


thanks!

drill it and don't forget to smooth the edges on the inside AND outside of the hole. You don't want to cut your stem.

most rims will take it.. make sure you remove the burrs in the hole and smooth the edges, not only does it keep from cutting the stem but it keeps the rim from having weak points around the hole (mini tears in the metal left from drilling need to be filed out so they don't become larger tears)
