Frederick Henry Grubb (27 May 1887 – 6 March 1949) was a British road racing cyclist who competed in the 1912 Summer Olympics. He won silver medals in the individual road race and the team road race. In 1914, after he retired from racing, he established a bicycle manufacturing business (F.H.Grubb) in Brixton, London. By 1920 manufacturing had moved to Croydon and then in 1926 to Twickenham. In 1935 FHG Ltd was established in Wimbledon but by 1947 the F H Grubb name was back in use. Two years after his death the business was bought by Holdsworth, which used the Freddie Grubb brand until around 1978.
