The Speedsleev Ranger is the next evolution, set up to be extremely tight fitting saddle bag that carries all the essentials. Too many saddle bags are either too big or too small, rattle or hang and the Ranger eliminates that. It can fit 1-2 tubes depending on size, has two specific CO2 holders, will fit a couple tyre levers, inflator, and multi-tool. Everything you need on your ride.
