i keep thinking of things, the frame was a custom build by Les Holland one of the partners in Knight Cycles, when it was explained that the intention was to carry a young child in a seat on the rear rack he was concerned about how to securely mount the rack to the seat stays, he had a think as the he felt the off the peg braze on mounts would not be strong enough, in the end he modified two braze on lamp brackets intended for the front forks which allowed a much more substantial bolt to be used when securing the rack to the seat stays.
I wanted to discuss etc my wife's 30 year old Knight bike but as a first time poster I am not sure if it is considered ' Vintage ', I have to wait until I have permission to post a photo but just wanted to know if i was in the correct area ?
