Come on now be realistic (or don't your fantasy is kind of funny). I am sorry having talked to other mechanic friends who have been doing it longer than I also haven't seen the need to adjust 10 times.

Because I have dealt with a lot of hangers over time but I don't come across a lot of weak ones I think your statistics are made up or you sell bikes that are so bad that nobody else is selling them or working on them. You seem to replace hangers a lot more often than most people so I would imagine it is something you are doing or are just lazy as we discussed mechanics could be earlier.
