My daughter has a 1978 Grand Jubile and right after she bought it I took it to a bike shop to buy new tires for her run by a guy who raced and actually knew the ins and outs of these bikes when they were new. After putting new tires on her bike , he was mounting the front wheel and said the alignment of the fork was off. He showed me his gage and then he got out his tool and with some persuasion was able to align the fork. He let me watch him , I had never seen that level of work done.
