I was thinking about the stopping power of the old Weinmann brakes and remembered how I damaged the rear wheel on my Holdsworth. It was back in the 70's and I was chasing a mate to work, he was in a car ahead of me when he braked hard. There was no other option than to grab a handful of brakes, the front wheel locked and I went over the handlebars, the rear wheel slamming into the road buckling it.
The brakes were Weinmann centre pulls with pink ish brake blocks on ally rims and seem to had enough stopping power in their day.
