Shimano HG300 8-Speed Cassette

The Shimano HG300 8-speed cassette (model CS-HG300-8) covers a range from 11 to 45 teeth and is designed for road and gravel use. The eight sprockets have 11, 13, 15, 18, 22, 27, 35 and 45 teeth: the smaller sprockets provide speed on flat roads, while the larger ones help tackle more demanding climbs. The sprockets are made from steel.

The range is 11-45 teeth: to assess how easy climbing will be, compare the largest sprocket with your bike's chainring. Before buying, also check compatibility with your hub, as the technical specifications list a Shimano MTB freehub, while the product description states Shimano HG; it is advisable to ask the retailer for confirmation before ordering.

Founded in 1921 in Sakai, Japan, by Shozaburo Shimano, Shimano is still based in the same city today. For cyclists, it makes drivetrains, brakes, wheels, pedals and cycling shoes. Its history in bicycle components began with the production of freewheels in 1922.
