Popped in yesterday with a broken rear derailleur hanger, broken mech itself and snapped chain.
Left with new parts satisfied
The chap in the workshop took time out of his day to inspect the broken bits I had brought in. After looking at them for all of 0.2 seconds he trundled off to his big box of smaller boxes, out pops another smaller box. There low and behold all the parts I required, he explained in layman's terms how to fit, fiddle and tune them - top man
Excellent customer service
