I have both the Lezyne pressure(M) and Blackburn AirStik and both are adequate for emergencies and can get tires to 80-100 psi. The lezyne is cool with the concealed tube and it looks good too. Both will take alot of stokes to get that pressure, but for 100 grams of weight, and minimal use if you keep fresh tires, it is a compromise. My advise is to bolt the bracket to the water bottle holder and keep the pump on the bike. I previously carried the Lezyne in my back jersey and last season the one time I forgot to bring the pump, I got a flat. Murphy's Law.
