Title: Right angle tyre valve stems
Post by: PaulF on May 26, 2018, 06:38:45 AM
When I purchased my Like (125) I wondered why there was a right angle valve stem on the front and a straight one on the rear which was hard to get at so when I had new tyres put on my new 200i and the fitter asked if I wanted a right angle valve stem fitted to the rear I agreed and it has made checking the pressure and pumping in air so much easier.  My really good air gauge would not fit the straight valve so I had to use a cheap one on the back and I had to struggle to get my foot pump hose connected but now it's all good and I managed to buy a good slightly used hand pump off ebay with a clip on hose that is quick and easy to use.
Why they don't fit right angle valve stems to both wheels at the factory is confusing.

I agree - the straight one on my rear tyre is also a great annoyance to me!

I don't know if they do that for a reason or just to save a few cents but here is a good article on cheap parts being used that leads to recalls.

Bet it has something to do with how the wheels are presented on the assembly line?
Gas station air hoses on the rear are easy. But getting a gauge in there is a pain without a right angle one.  (Amazon)

I prefer to check my tyres at home and adjust when cold and for some reason I don't really trust the accuracy of petrol station air pumps.   I have a Jamec Pem tyre gauge that I do trust though.

I put a right angle one on, and it got smacked by the cvt body, and so, it can't be 90 degrees out like shown in the pic, but 45 degrees only, which puts it up close to a spoke, so causing issues, as I had to bend it at a crazy angle to get the air pipe adapter on, and splitting the rubber valve resulted, so I removed them again.
Just my experience on my xc500.

Yep, agree about the gas station air hoses - but it's a easy way to get air in that awkward back tire. Then I check with my gauge.

Sounds good Stig.   :)

I have one of these Campbell-Hausfeld compact pumps and it allows connecting to the rear valve easily. I then use a dial type gauge to check.

You can buy 90 degree valve stem extensions on ebay that solve the problem...or you can fairly easily remove the straight stem and install your own 90 degree valve stem without removing the tire or wheel (See my method recently described in the Technical column).
