I have the RoadMorph, which is amazing, and a very small frame... and it doesn't fit on it. And I hate carrying a backpack.

So for now I am sticking to CO2 but I still think I should get a small pump that would fit my bike just in case... even if it doesn't inflate to 100 psi, I can at least ride to somewhere... In the meantime, I usually ride quite close to civilization so it's not too much of a problem... But it will nonetheless be fixed at my next visit to the bike shop.
