Replacement inner tube for trials unicycles with 19" rims. Made with thicker rubber to help prevent pinch flats, especially for trials riders.
Until recently trials riders had to put up with standard 20" inner tubes in their trials 20 x 2.5" tyres. Running a standard 20" inner means that the rubber of the inner tube is stretched paper thin and is vulnerable to pinch flats. This new 20 x 2.125" inner tube is correctly matched to the tyre's size, and fixes this problem. These inner tubes are not available through bike shops. Once again Unicycle.com brings you the goods!
Note: this inner tube will only fit unicycles with 20 x 2.5" trials tyres, such as the KH20, Onza trials and Nimbus Trials unicycles.
