Valve stems for spoke rims?

Maybe I messed up?

I recently had Cycle Gear to change a rear tire and while there they offered an angled valve stem. I was really happy to get that put on, but for one, it's angled, not 90 degree as I thought so it has practically made access harder, rather than easier, and secondly, it seems I have a very slow leak, possibly.

I just noticed that Wunderlich has a 90 degree "for spoke rims, not cast." Is that because a cast rim stem won't seal in a spoke rim? (FYI I have spokes).

Basically my question is, did I get the wrong valve stem? If this is something that can cause a long term leak I'll get it replaced. Otherwise I'll wait 'till I need another new tire.

If you are going to ride your bike on road and not in loose stuff off road the angled stem seems to make sense..but just for me a 90 degree stem doesn't work for my off road riding..it is too vulnerable to getting ripped since it is oriented 90 degrees to direction of rotation...I try to reduce all "what ifs" that could cause a component failure....can't ever make it bullet proof but often a little thought can give you an edge..

Putting air in or gauging pressure is more about technique that angle of stem...just my thoughts.

Did you soap test the stem to see if it is leaking? Most often it is the stem valve and not the stem..

Good advice. Also, make sure you're fitting the correct stem cap with o-ring.

I've had them on for about 20K miles, and love them!

There's no such issue with the spoked wheels, no mods needed

Correct. My friend Kermit has had his on the spoke wheels for about 30K miles! Great stems for the price!

Ordered mine

This will be my 4th Tire change in 33K miles. So, since I am doing front and rear decided to get the stems Jimmy V told us about from Motosport. These are the 90deg. ones for my 08 GSA with spoke wheels. Hope I have good results. Wont miss fishing my air chuck through the rotors on the front.

I've used these types of valves on both cast wheels of my old Fireblade and the spoked wheels on the Adventure,





When I bought these types back in the late 90's I had to source them from Italy. They were kind of expensive to do that way.
These I got from Wunderlich.
These have been in my wheels since about 2005 I think. I can't remember for sure. I have replaced them once each end.
