I carry a frame mount( under the top bar) Topeak Road Minimorph and a CO2.You mini seems like it would be harder than hell to hit 70 psi muchless 90-120 psi. My roadmorph to me being disabled is hard to pump to 100psi( my rear tire pressure, 90 psi front).Like they say, you only have air if you have carts!I always have air!
