I don't know if this will help, but this is how a pedros bag fits on my bike with an smp evolution which i believe is 129mm wide. This is the small bag, or maybe the medium. It's the one right above the micro and I have 2 co2 catridges, 2 tire levers, co2 chuck, tube, patches, zipties, gloves, small multi tool, and an ID in it.
