90 Degree Angle Tyre Stem Valve

[Mold]

Hello, has anyone got any experience with these angle valves and are they any good?

I did try the screw on type but they leaked, these look ok and I'll have to get them fitted when I get new tyres, I know they're not expensive but are they worth getting?

Thanks

I bought a pair of those very same ones. My mechanic didn't want to fit them, he said something about centrifugal force making them leak. 

I brought them because I was always having to top up my tyres. It turned out to be corrosion where the valve was seated. Once sorted, I opted for the Bikeit indicating valve caps, they're brilliant, I haven't had to go near my valves for two months, as I can see at a glance.

Thanks for your reply Simon, I might try those that you mentioned. I wanted the angle valves because it's a bit of a carry on getting to the valve on the back wheel.

I bought long ago the 90deg adaptor.

You can get a pair for next to nothing and you just put them on when you need and they are easily stored in a small place

My bike has right angle valves as standard and guess what? They don't leak.

Indeed, I didn't think they would leak. I think they're a good idea, but I was swayed by my mechanic, who'd ended 9 months of misery from my poorly running bike and leaking pressure from both wheels. 

I don't see why they would leak either

They don`t leak and are fantastic at avoiding damage to expensive Dymags from the filler nozzle. Also standard fitment by several manufacturers including Guzzi, BMW and Indian just from a straw poll in my garage.

Definitely fit them but in the meantime zip tie one of the screw on ones somewhere on the bike.

if it’s standard oem fit then fine.

but Depends on the wheels, some are better designed for them (got to remember about the inner fitment not just how it looks on the outside.

most straight ones have two seals (inner and outer rim, those ones you have there only have one which is the outer side only, plus the screw nut might dig into the alloy or steel, ok when racing but when long term road use they have a compromise.

true to the point of centrifugal force and a slight weight balance if you have a awkward rim it can do, and that’s why you’d have to clamp the thing down harder and give the rim some extra grief.

just make sure you get the correct size t

as they come in different sizes as I found out on the triumph.

 

what ive done is used a screw fit nozzle and hose (from a high pressure bicycle suspension pump 250psi job) on my motorbike/car tyre pump-

 

and just screw fit the thing on as valve has a external thread-

most I’ve ever lost is 0.25 of a psi in summer while in the process of unscrewing it even I screwed it back on to recheck it, it’s been the Best method for me. 
 

rather than the normal push or clamp on ones, which are terrible and potentially do more damage to the valve.
