The Lezyne Road Drive Pump has a ton of great features. It is light weight (the Medium size is only 90 g). It has a section of hose that attaches the pump to the valve so you don't rip your valve off when trying to air up your tire. It has a very smooth pumping action so your arms aren't as tired when your done. It has a great mounting bracket that is made from alluminum and has little rubber bumpers so your pump stays in place and does not rattle. This is a great little pump. Presta valve only.
