Brake a few weeks back grabbed for a couple seconds and managed to bend the arm that connects to the frame. I had this thing apart when I got the bike to make sure of lube and two other times. The question is, can one take the paws out leaving the rest inside and then do away with the arm? I have caliper brake on the rear now and it does a good job. If I can't , going to do something different. Don't care much for the Cranny hub back there but then don't know too much about what is quality here anyway. Continuing learning experience. gphil
