Review on 🚲 Ultimate Bike Alignment Tool: BW Bicycles Derailleur Hanger Alignment Gauge for 20” - 29” MTB and Road Bikes by Josh Parson

I got mine yesterday and got to work. my observations. Some people have noticed slight play, which I believe is due to the bend in the switch mount. As with any bend in metal, there is a slight bend just past the end where it should end. It didn't take long to figure out how much it was around the rim when adjusting. I didn't take into account that the mount is not centered on the axis and that the sensor has to move up and down the rail for each measurement. Don't worry, he has enough resistance to be safe and not so much that he needs to be forced. The resistance on all parts seemed well thought out. Of course, my "daily driver" was wrong both vertically and horizontally. The entire process for one bike took about 10 minutes, including time to clean some of the parts exposed when the derailleur is removed. Bikes known to fall on the right side.
