Daysaver IncredibleX & Pump40HV: Lab Tested Review

Jennifer Miller · 2026-06-12

Integrated bike storage is one of the biggest trends in cycling right now, and for good reason. Nobody wants their pockets bulging with tools or their frame bag rattling like a maraca. Daysaver offers a sleek solution with the IncredibleX multitool and Incredible Pump40HV, letting you stash essential gear neatly out of sight. We put this system through its paces in both lab and trail conditions to see if it lives up to the hype. ### The Incredible Pump40HV: Small but Mighty Pack size drove every decision in the design of the Incredible Pump40HV. At just under 5 inches long, it fits easily into a jersey pocket, a frame storage bag, or the chest pocket of an EVOC Hydro Pro without complaint. Despite its compact dimensions, it delivers a solid 40 cc stroke volume, which is impressive for something this small. The optional hose is the standout detail here. It screws onto the valve but is engineered to release cleanly on disconnection, eliminating that infuriating habit shared by most screw-on systems of pulling the valve core out with it. That alone is worth the price of admission for anyone who's been stranded on the trail with a busted valve. The pump also doubles as a storage housing for additional Daysaver tools and can be mounted to a bottle cage or tool mount using an optional bracket. But ergonomics are a weak point. The pump cap has a square-edged shape that digs into your palm when inflating tires to higher pressures, especially on road bikes. It gets uncomfortable fast. ### The IncredibleX: L-Shaped Design for Better Access The IncredibleX is being replaced by the Incredible8, but the two are essentially identical. The only real difference is the bits they include. The IncredibleX uses two-piece bits, while the Incredible8 uses one-piece versions. The two-piece bits will remain available separately, so flexibility isn't lost. For most riders, though, the lower price of the Incredible8 will be the bigger draw—it costs $22 less than the previous model. When unfolded, the IncredibleX stands apart from conventional folding multitools with its distinctive L-shaped design. This layout improves access to bolts that traditional tools struggle to reach, like those tucked behind disc brakes or in tight frame corners. Leverage is excellent, which becomes particularly noticeable when loosening pedals with the 8 mm hex key. The bits and bit holders are easy to handle and can be swapped effortlessly, even while wearing gloves. ### Where It Shines and Where It Stumbles Storage flexibility is the system's standout quality. The tool mounts inside the handlebar via adjustable end plugs that expand mechanically rather than relying on friction alone, making removal cleaner than most. It can also sit inside the pump body, and in either configuration, it remains rattle-free. A OneUp steerer mount works just as well. But there's a catch. During testing, one of the bits broke. The modular pin-and-magnet connection is sensitive to incorrect installation, and bits that aren't fully seated in the holder can fail under load. It's a design flaw that could leave you stranded if you're not careful. ### Final Verdict on the Daysaver System The IncredibleX and Incredible Pump40HV make a compelling case for riders who prioritize clean, integrated carry. Modular compatibility, thorough spare parts support, and build quality that justifies the asking price are the headline credentials. The L-shaped layout adds genuine access advantages that a straight tool cannot match. - Clean workmanship and premium material quality - Versatile integration options including handlebars, pumps, and various tool mounts - Excellent leverage for tough bolts The honest obstacle is the price. Those willing to absorb it get a system engineered with care and calibrated for daily trail use. For everyone else, there are cheaper alternatives that get the job done, but few offer this level of integration.
