The Linear inner tubes are straight tubes designed with a joint to lock the two ends together thereby removing any gap.
The joint system is designed with a tongue on one side and a groove on the other end. This will allow inner tube changing without having to remove the wheel! No more hassle and getting dirty when taking off the brakes or the chain off the gears to take off the wheel kit, and no worry about how to put them back on. Additionally, the joint lock system prevents any major wear and tear, and lasts a long time.
It is perfect for cyclists who need a quick, easy solution. The tubes are also great for bikes with bolt-on wheels such as BMX, fixie bikes and internal geared hubs.
