Yes i considered that as an idea also. Having everything in a bag is a good thought, but as I had the larger pipe left over from the Yam job, thought that the better option. The main cruncher for me was losing the option to fit a more dirt oriented tyre. Even with around 12mm clearance, a bigger dirt tyre, partially deflated, is going to flex enough to rip the tube off most likely. I have'nt written the idea off completely yet and i'm thinking spacing out the pannier frame a little may just do it, as long as it does'nt look silly. The thing's wide enough with the boxes on as it is.
