Received on time, from USA to USA. __These are not 90 degree offsets, they are 85 degree offsets. When using an external tire monitoring system, clearance issues may arise. I was able to bend one slightly to make room BUT BE VERY CAREFUL not to break the metal rod. __ARD PROBLEM. __The valve works fine but the 2 rubber seals that go to the rim are POORLY constructed, they are SOFT. Tighten and they will burst. I used "Permatex 2" on both sides of the rim and fixed this very slow air leak problem. __(TIP TO DESIGNERS!) A better design would be nuts on both sides of the rim AND stiffer rubber rim washers. They do NOT cost more.
