This is the perfect size, not too big, not too small. It fits a tube, levers, 2 CO2 cylinders, inflator, Allen wrenches, latex gloves, and $s for a beer after a long ride. Only downside is the corners on the Velcro that goes around the seat tube are sharp. I rounded mine off with a scissors and melted the ends. I like this enough I bought a second for a different bike.
