Years ago I dinged the front Campagnolo alloy wheel on my Ducati a pothole in the Cromwell road. For once, the excellent Bernie's Spares and Repairs in Collier's Wood didn't have a spare in stock, and with the summer factory shutdown in Italy, no chance of e new one before mid-September.
I got the rim straightened by Alf Hagon up in Leyton, and then one of the guys in the Ducati Owners Club who worked as an engineer down at Heathrow took it and got it crack tested at work (for free).
