Snapped a hanger last week, finally got round to trying to swap it last night as I've been riding other bikes and waiting for parts etc.
Problem is that someone's been here before me.
There's the remains of an Allen key jammed in the bolt on one side.
Obviously, tiny countersunk steel bolt in very aluminium frame, right on end of chainstay so plenty flex.
Ideas ? All I can think of is drilling/smacking off the head and hoping I can moley the remains out although the dropout will make purchase awkward. I don't see slotting the head working well this time. Don't have any welding kit either...
