And despite all of that, it’s rattle-free – something many simpler pumps fail at. This 100cc version offers space for a multi-tool, chain breaker, tire lever, chain master link and CO2 canister. Instead, you can store the customisable tools inside your pump barrel. OneUp has designed its pumps to work with its EDC tool system (US$59) that are best known for stashing inside a fork steerer. That Presta-only head can also be removed and used as a CO2 head.īut that’s hardly the only trick here. The Presta-only press-fit head is no-fuss, and the pump will fill a tire before you start wishing it had a hose. The machined aluminum construction gives it a quality feel and plenty of grip in hand. It’s the only pump on test that goes beyond traditional inflation needs, and yet, it’s one of the best pumps, too. * Extra features: Pump head doubles as CO2 inflator, bottle cage mount, can store OneUp's EDC tool (US$59) inside barrel. An even longer, original, version of this article, which covers high-pressure pumps for road-use, is published on. First, it’s the winners, followed by information on selection criteria, testing protocol and features to seek. And while I’m still yet to find perfection after having tested over 20 well-respected high volume mini pumps, I’ll happily settle for a few of the better options. And a select few, by comparison, were almost a joy to use. Some were a fiddle, while others simply rattled consistently when not in use. This is the most physically painful test I’ve done to date, and while the majority of mini pumps tested put the desired amount of air into the tire, some took a significant and tiring effort to do so. For that, I wanted to know which ones were worth carrying, and which should be avoided. However, almost every time I’ve used a mini pump I’m left painfully aware of how inadequate some of them are. Will it work as intended? Have you accidentally pinched that tube you’re about to fill? Are you about to give yourself a freeze burn? And what if you flat again? A pump saves panic. However, if you’re not racing, CO2 is wasteful and carries an element of risk. For years I’ve carried just CO2 on my rides and hoped for the best, or cheekily relied on others for a pump on more remote adventures. To change the compatibility of the pump, simply turn the insert around.When it comes to putting things on my bike or in my pockets, I’m a minimalist. It has an insert compatible with Presta valves on one side and Schrader valves on the other. The Twist-Lock valve head is placed on the tyre valve when open and then fixed in place with a rotating movement so that it closes around the valve. improved dust protection cover, also prevents unintentional opening.both chambers are made from aluminium for more durability.a CNC-machined body for a secure grip during tyre inflation.Twist-Lock valve head minimises size and allows easy switching between Presta and Schrader valves.Invert Design with a double chamber system (the hose outlet is located on the piston shaft, the cylinder is pressed over the piston) improves performance by about 28% compared to the predecessor.Specifications: Design: mini-pump, frame pump Type: high volume Pressure (max.): 4.1 bar (60 psi) Valve Head: Schrader, Presta Technical Information: Air Volume: 100 cm³ Material: Aluminium Features: The pump has an easy to grip aluminium body and is supplied with a bracket for mounting on bottle cage threads. Maximum flexibility is provided by the Twist-Lock valve head, which is compatible with Presta and Schrader valves via a reversible insert. Due to a revised design, performance has been increased by almost 30% compared to previous models, making it easier to inflate the tyre. The Air Tool MTB mini-pump from Specialized convinces with its large volume. The Specialized Air Tool MTB mini-pump - extra power
