Vincent racing motorcycles were fitted with a special and simplified chain adjustor.
Racing models were supplied with a T-bar adjuster and locknut. These were not present on 2751 though they were originally fitted.
David Dunfey kindly put me in touch with Vic and Matt Olsen, who were making some, and they agreed to make me a pair.
These were made from the drawings published by Frank Griffin and Eddie Stevens in a series of articles titled ‘Throwing Light on some Obscure Components’. Thank you gentlemen! And what a great resource the VOC is.
