SILCA Hiro V.2 Presta hogedrukpompkop met zijdelingse hendelvergrendeling 2019 reserveonderdelen

Excellent tool for the basic use of filling Presta Valve tubes/ tubeless tires. For my MTB, I use it with a Milwaukee tire inflator and it is a perfect pair. Excellent Build quality.

I've read all the positive reviews on this with the only negative being the price. Price didn't bother me as long as it was a good product. I've watched the online vids, I'm deffo using it correctly but this is the leakiest thing ever. It's worst than our defence and I'm a Liverpool fan. It's going back.

Durch die teils doch sehr durchmischten Rezensionen war ich schon vorgewarnt und auch in meinem Falle hat sich der Pumpenkopf als nicht praktikabel erwiesen. Egal in welcher Einstellung sich die Verschraubung der Dichtung befindet, ob fest oder weniger fest, der Kopf ist am Prestaventil einfach nicht dicht zu bekommen. Alternativ habe ich es nun mit der Metallversion des Topeak Twinhead versucht, der im Gegegnsatz zum Silca tadellos funktioniert.

Works very well on TPU tube valve stem, adding significant value, but great on standard valves for tubeless setups and butyl tubes, too. No stressing stems with traditional clamp on heads, no unscrewing valve core when using screw on heads. Adjust preload, push on, turn lever, get immediate pressure reading, and pump.Easy to use, versatile, and better for valve stem health.

Bought this chuck after reading about the most expensive Chuck on the Planet and found that it is (almost) worth it's high cost. There is nothing else like it, and it really does work. Do you need it? Probably not, but if you can spare the change, it really is a game-changer when it comes to convenience and ease of use. No more fumbling around to keep a lesser chuck on the valve, this one works the first time, every time. It does take some adjustment to get it to bite on the valve stem, and the polymer seal will last a lot longer on unthreaded stems, but is easily replaceable when it wears out.
