The Lezyne Sport Floor Drive is practically the same as the Lezyne Alloy, while being a little less stylish and a little more portable. It comes in a 1/2 pound lighter than the Alloy, and that plus a solid composite base meant we were quicker to toss this into our cars with all our other equipment. It has an extra long hose, making inflation of almost anything more convenient, and a flip thread chuck, which takes getting used to, but once you are threading it properly, provides a good seal.
The Sport Floor Drive is just what it sounds like — the sportier sister to the sophisticated Alloy Floor Drive. They are basically the same pump, except the Sport has a beefier black base and dial, and a simpler wooden handle design. That said, they scored the same across most categories, except the Alloy out-ranked the Sport in terms of looks and design, while the Sport showed a slightly tougher portability aspect.The Sport has the same extra long hose, which really helps when you are trying to inflate something inconvenient (such as a bike in a bike stand). Also, even though it can be a bit of a hassle to get the threading right, once you've attached the chuck to the valve, the seal is secure and reliable. However, the sport also has the silver background on its gauge display, which tends to glare in certain lights and can be a pain when you are trying to read your psi.
