PRIMO's own 9 Inch Inner Tube has dimensions of 225mm (outer diameter) x 65mm (width) & will fit into all known 9 Inch Tyres & ATB Hubs on the market!
The CST PRIMO Inner Tube incorporates slightly thicker rubber into its manufacture process which means the tube is slightly heavier than alternatives but does allow the rider to inflate slightly higher. This extra thickness also gives some extra resistance to punctures, but punctures suck, so always carry a spare inner tube when you are riding as you never know when you might get one.
The PRIMO Tube uses a 90º Brass Inflation valve which will not rust on you & comes as you would expected with a plastic "anti dust" valve cap!
