Reg Harris Bicycles were made by him in Macclesfield no connection with Raleigh. He started this business when Raleigh aimed him out. Gerry Burgess (GB), Harry Haselton (Ex Elswick Hopper) and I believe Arthur Whatmough helped him get started. He was bloody fuming with Raleigh when they finished him. Peter is correct in saying that he won his British 1974 comeback sprint title on one of his old Raleigh track bikes, this was loaned to him for the event by Raleigh's. Reg Harris cycles was relatively short lived but there top of the range bikes were half decent. Ref: Two Wheels to the Top by Reg.
