Valve stems

[johnparjr]

I wanted to replace on my wife's bike the 650R the stock vavlve stems with some 90' degree ones how hard is this and are all valve stems the same size??? Inquiring minds want to know and any answers appreciated :)

I believe all or most japanese wheels are 11.3 mm. Not any more difficult then replacing the standard stems.
I'm guessing you're talking about aluminum stems.
Rubber 90 deg. stems are bad news. I've heard of them failing due to centrifical force.

If you find a good source, let us all know. I've been meaning to get a set myself.

I've sold many sets of 90degree valve stems and currently have them on both of my bikes, wouldn't want it any other way
