Ever since I've begun riding a bicycle longer distances from home, I never go without slime in my tires and a pump on my bike. I hate having thorns ruin my ride so I don't let them any more. I have had my air pump for a couple of years now and it still serves me well. It can reach high air pressures without some of the heating other pumps experience. I love the dual direction pumping which allows for faster tire inflation. This is especially important when I'm out on a ride with friends and I don't want to slow them down. The compact design allows me to fit this pump on my frame in places other pumps don't fit. I can also throw it in my back pack when I'm commuting to school. I also appreciate the light weight design which in no way compromises the durability or function of this excellent pump. The method of adapting from schrader valves to presta valves is a little awkward but I can't complain for the price I payed for it.
