ya i have a small top peak master blaster dx, that mounts to the water bottle threads, underneath the bottle holder(so you dont loose a water bottle mount). sits off to the side, if you wear normal shorts(im a novice) they can catch, but not bad. it takes a little while to get up to 100psi, but not too bad. i dont even bother trying to get up to the 110-115 i run my tires at, because it is too much work, but 100psi is not too bad. it is a presta/shrader valve, "auto adjusts"....honestly it doesnt work too well on shrader valves, but i could give a F#$*! it was $19. oh and always have a least one spare tube. i also keep a spoke wrench, a set of 3 plastic tire levers(the snap together), and a small led flashlight...
