Reviews
These are a true 90 degree valve stem with the valve stem being very near the center of the tube. These tubes work very well for the Azusa 2 piece experimental wheels. The Azusa 2 piece wheel is a split wheel with the with valve stem placement in the middle of the wheel. Meaning that each half of the wheels has a 180 degree cutout for the tube valve stem. A true 90 degree valve stem is required for this application. The rubber thickness is near heavy duty on these tubes as well. Be careful as some tubes that claim they have a 90 degree stem are actually 45 degrees and the stem is offset further tpo the side of the tube.
Tube is of good quality, good 90 degree bend but valve is not on center. I also had to modify rim to make them work.
Another reviewer said These are a true 90 degree valve stem with the valve stem being very near the center of the tube. I ordered the Azusa tube #7125, and the 90 degree valve stem was NOT even close to the center of the tube. It was about 25% of the way around the tube. I ended up modifying my wheels and moving the valve stem hole to better accommodate the offset valve stem. If I ever do end up with a proper tube, it will still fit the wheels!
