The Lezyne Sport Gravel Drive is the ultimate floor pump for gravel riders! Size matters The size of the pump chamber is in between that of a floor pump for road bikes and a floor pump for mountain bikes. This makes it possible to inflate tyres with a tyre pressure higher than mountain bike tyres and lower than road bike tyres. This pump is therefore ideal for gravel tyres! All the more so because the pump head is also suitable for use on threaded Presta valves without a valve core, making it easy to pump a lot of air into the tyre in a short time. This makes it easier to seat a tubeless tyre in the rim. Construction The pressure gauge is large (diameter of 88.9 mm), so that you can accurately read the tyre pressure up to a maximum of 6.9 Bar (100 psi). Furthermore, the sleeve and internal components are made of robust steel. In addition, the foot is made of hardened plastic for extra stability. To top it off, the handle is made of wood and ergonomically shaped for ease of use. In short, this pump not only provides excellent performance and all the necessities for gravel riders, but also a stylish and durable appearance.
