This derailleur hanger is a great fit for multiple bike models. It's compatible with various Focus bikes like the Whistler Elite 29′ (2016 - 2018), Bold Pro 2017, Create Lake, and Aventura. Also, it works well with Kalkhoff's Endeavour and Track 1.0 cross series bikes.

Using this derailleur hanger is easy. First, make sure your bike is one of the compatible models. Then, carefully remove the old hanger and attach this new one. Ensure it's tightly fixed to avoid any issues. When riding, pay attention to how the gears shift. If you notice any problems, stop and check the hanger. For maintenance, clean it regularly with a soft cloth to prevent dirt and debris build - up. Avoid using harsh chemicals that could damage the hanger. Store it in a dry place when not in use.
