Right, 1. My left maggie cylinder on the rear keeps on slipping, even when the bolts are tightened right up, ive checked theplastic ring in there, cleaned the actual maggie ( so theres no loose paint, grease etc there) the mounts aren't threaded, the plastic bits make no difference and yes they are tight.....why?! 2. My rear wheel slips sideways in the droputs, almost dropping out of the frame occasionally, im sure its the qr skewer, but is there anything i can do about it short of replacing the skewer? is there anyway to convert QR to bolt through?
