To pressurise voluminous MTB tyres, you need stamina or a so-called high-volume mini-pump. These powerful pumps are designed to inflate fat tyres particularly quickly. Crankbrothers put the Klic HV to the test and aims to entice technology fetishists with smart detailed solutions, a folding handle and CO2 adapter.

Crankbrothers Klic HV CO2 mini pump - Features

The features of the Crankbrothers Klic HV are impressive. It has a folding T-handle in which the extension hose is concealed, a CNC-machined pump head and a magnetic coupling that connects the hose to the pump. The attachment point for the hose can be closed using a rasterised rotating ring. There is also a CO2 cartridge attachment in the lower end of the mini pump, which guarantees quick tyre inflation in an emergency.

Handling / processing

In an emergency, it turns out that many of the features are more of a gimmick. It takes a while before the mini pump is even ready for use. Fold down the T-handle, remove the hose, open the coupling point, attach the hose and screw it onto the valve. If you also have to change from Presta to Schrader, you are almost finished inflating with other models.

Once the Klic HV is ready to go, it sits comfortably in the hand thanks to the T-handle. Caution: If you don't grip it properly, you can easily pinch your fingers. Otherwise, pumping with the Crankbrothers is quite comfortable and the 90 degree angled hose creates a comfortable pumping position. Annoying: If you transport the Klic HV in the holder on the frame, the hose rattles in the cylinder while riding.

Pumping capacity / manual force

Due to its short design and slim cylinder, the volume of the Crankbrothers mini pump is manageable. We needed an average of 183 strokes to press 1 bar into the tyre. At least the hand forces when pumping remain pleasantly low and the T-handle improves handling.

Conclusion & evaluation

With all its gimmicks - rotating dust cover, folding handle, magnetic coupling, CO2 attachment - the Klic HV is a nice toy for technology fans. However, other pumps are better suited to the "real thing". You need little effort, but a lot of strokes to pressurise the tyre. The folding handle is a bit angular, and you can easily pinch your knuckles when pumping if you don't grip it precisely.

* Note: Weight, size and pump strokes per bar are BIKE measurements. We measured the pump strokes per bar with a precision manometer on the volume corresponding to a 29x2.35 inch tyre. The maximum pressure is a manufacturer's specification.
