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 have the Motorcycle anchor vavle stem.It's not marked for cast or spoked wheels, it's marked for tubless tires only. (:doh)

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

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

I looked at these once before, then forgot about them in the midsts of my other travails. How do you and Kermit have them pointed? Out to the side? Along the plane of the circumfrence? ...
I have spoke wheels.

I have the MotorcycleAnchor stems also and love them. Much easier to air down and air up for dirt riding. I mounted them at a slight angle directed at the gap between the spokes for easy access. Many K miles including Alaska with much dirt and have had zero problems. Muuuuuuuch easier access especially on the rear. One of the best mods I made.

To the side. Pick for yourself left or right. On the right is easier on the front for the sidestand, on the left for the centerstand. Keep in mind that the left has a little issue with the brake rotor blocking as easy of access.

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 had no issues with these on K1200LT cast or R1150GSA spoke wheels.

No modifications required.

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.

onesaintsfan 01-23-2013 03:53 AM

I mean
 
I ordered the ones from www.motorcycleanchor.com . The vendor is not too sure of what they are selling it seems.

onesaintsfan 01-29-2013 05:28 PM

Got mine today
 
Look to be good quality
