The Scummer's been an absolute joy since the rebuild, and I've been out getting in some long hard k's while the tracks have been drying out after the rain. But, disaster struck last week, a 'slam' gearchange, going onto the big ring at the front while shifting to one of the bigger cogs at the back with too much load (I should've known better), and the rear derailleur twisted out of the hanger, stripping what was left of some very tired thread after nine years of use. With a road bike, the hangar is usually permanently attached, and in my case, bonded into the carbon frame.
