Shadow plus axle bracket unit alignment

The axle bracket unit can get easily bent out of shape along with your derailleur hanger.  If you have a derailleur hanger alignment tool, then you can also use it to align your the Shadow Plus axle bracket units - the thread is the same as the derailleur hanger thread.

Process is as follows:

• remove rear derailleur from derailleur hanger;
• align derailleur hanger using alignment tool;
• refit derailleur and remove derailleur from axle bracket unit, leaving axle bracket unit connected to derailleur hanger;
• thread derailleur hanger alignment tool into axle bracket unit and align axle bracket unit, taking care not to bend derailleur hanger in the process.
