Rear Cogs

Shop here for Australia's largest selection of rear BMX race cogs. We have the cogs that fit the popular Shimano HG style cassette hub, Profile cogs for Profile hubs and Onyx cogs in aluminium and stainless steel on both HG and Ultra SS fitment.

While you're changing up your drivetrain, once you have the cog, jump on over to the Chainring section and then the Chain Section to refresh the whole power train!
