A LBS near me is having a everything-on-sale sale and Ive been looking for a co2 pump. How many people here use one? Should I look for threaded/non threaded compatibility? Anyone have a co2/pump combo? If so, is the pump able to get to road tire pressures? The combo ones I saw in the LBS could only go to 75 psi, I might as well ride on a flat. I would just like the security of having the pump AND the co2. What models does everyone have? I think the sale ends today so any timely responses would be greatly appreciated!
