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

This tool is very easy to use and has virtually no play. I thought my new rear derailleur hanger was straight, but my SRAM X01 AXS was no longer shifting well. I had to adjust the horizontal angle of the suspension a few degrees to get the difference for accurate shifting in the lowest and highest gears. With the latest extra large switch cages, it doesn't take long for the shackle to bend slightly, and these switches are very sensitive to that. Highly recommended. I haven't tried the more expensive tools, but if you're not a pro, this is more than enough. Be very careful when inserting the tool to avoid cutting the mainshaft threads.
