So my question is. I have WTB LaserDisc Trail wheels on my Trance. Apparently they will only accommodate tubes with presta style valve stems.
I am OK with this except I have several right sized schader style tubes already and two other bikes here that use schrader as well. It would be nice to have all three bikes on the same platform of tubes.
I'm not suggesting I hack up my wheels with reckless abandon but the curious thing to me is that in looking at the inside of my wheel today (which I was so lucky to do midway through the hardest trail in the park due to a pinch flat) I noticed that the initial opening inside the wheel is large enough to accommodate a schader tube but the opening leading to the "outside" of the rim is presta only.
So my question is, would it be semi-sane to drill out the "outside" opening to the same diameter as the "inside" opening? Pics below show the two different sized openings. I'm guessing it's a bad idea but it sure would be nice to be all schader (don't have to use adapters, only have to carry one type tube in camelbak, etc).
What does everyone think?
