Wasn't sure where to ask this but I figured people that frequent this section might be best suited. I do alot of group rides as well as commuting. I'm looking for suggestions on a good quality lightweight floor pump. I currently use an inexpensive park tool one that is always full of problems, mostly the head doesn't always switch over from Presta to Schrader and I end up having to bang it on the ground to make it work. I carry it in my messanger bag (just put it across the top of the bag and close the flap, both ends of the pump stick out of each end of the bag). Between the muliple group rides I could end up changing anywhere between 2-10 flats a week (for other people/sag support) also airing up tires before the rides so the pump gets alot of use. Looking for suggestions on a lightweight, good quality floor pump that's not to awkward to carry with my messanger bag.(I don't want c02 or frame pump)
