i didn't even bother to see what they are, but if they're the kind that indicates the tire pressure by a red, green, or yellow band, forget it. they're very unsafe and prone to failure. some racing associations require a metal valve cap with an included rubber gasket inside to seal the valve stem. think about it, the centrifugal force can overcome the spring holding the plunger in place allowing the valve to open and leak at high speeds. that's exactly why you should only use metal valve caps with the integral rubber or neoprene, whatever they use for the sealing gasket. if you want some really trick valve stem caps look at what's available in the street rodding marketplace. loads of stuff in that area.
There was a thread about PIA to add air to tires and these came up not long ago. The poster liked them. That's all I can remember.......we can't use them since we have spoked/tubed wheels.
I bought a set Tuesday for my 09 Ultra and they're between FL and PA. I've read great reviews on this Forum that's why I bought them. The 09 wheels are such a PITA, I think they'll be a great improvement.
I think I search for "angled valve" in the title and that's how I found the thread. Or search for "motorcycleanchor" in the text.

If the voices in your head would have let you look at the link, you would have found a very good product that works as advertised. Even on the racetrack!
Lots of info on these on the forum. I have them and will have them on every bike I own from now on. Extremely well made and a perfect solution to the valve stem problem on the '09 + wheels.
