"Hey mate, can I borrow a tube?" How often have you heard this over the years at the track? Moral of the story? Always have a couple spare tubes in the tool box or car because nothing will wreck the ride more than copping a flat. Shop here at LUXBMX for Australia's broadest selection of BMX race tubes, from 18 inch micro tubes, through all of the 451mm (20 x 1-1/8 / 20 x 1-3/8th) rim sizes and tubes for pro sized wheels. Of course we have the 24 inch cruiser class covered as well. Presta and schrader valves across all of the sizes too.
