Pumped up.

If you've ever spent way too much time and expended far too many CO2 cartridges trying to seat a tubeless mountain bike tire with a floor pump better suited for skinny, high PSI road tires, you'll appreciate the utility of the Blackburn Chamber HV Floor Pump. It trades a low, 50 PSI/3.4 Bar max pressure for massive air volume to make quick work of airing up those knobbies, and its four-inch gauge lets you know exact pressures in both PSI and Bar measurements. Small touches such as a 47in hose for extra reach, a durably oversized main body, a hose keeper, and an alloy cap and lever on the pump head make this floor pump a lasting, convenient addition to your collection.

  • Convenient floor pump designed for tubeless tires
  • High volume air stroke seats tricky beads
  • Large, easy-to-read pressure gauge
  • Compatible with Presta, Schrader, and Dunlop valves

I'll Drink To That.

  • Familiarity: I've used it several times

I bought this pump to fill my tubeless tires. It worked...and it worked well. Previously I've used my best friend's motorized air pump, which works a treat. Recently I decided to come into my own on the mtn bike scene, and with this pump I didn't miss a beat. I'll admit, it was tenuous at first, but once I got it dialed in, it worked without fuss!

TLDR. If you need a pump for a tubless set up, this one works damn well! It also has a bottle opener attached to it, so that's good.

The correct pump for MTB's

  • Familiarity: I've used it several times

Nice, large easy to read gauge. Large volume pump. Comfortable handle. The valve head is easy to use and seals well. The 'camo' paint job needs to go. But, that's just me being picky. Overall, this seems to be the best floor pump for low pressure tubeless tires.

Pure Mountain Bike Pump

  • Familiarity: I've used it several times

I recently broke my pump that I keep in my car for summers and after getting a chance to use this one I was sold. I love the fat chamber and the insanely giant and accurate gauge. PLUS....the handle can be changed out for any pair of handlebars one might have lying around! Bonus! Pics coming soon. Who knew a pump could bring so much happiness

Fill Your Fat Tires Up Right

    Bought this on a whim, and sure am glad I did. I didn't really need another pump, but now I don't really use any other pump. This pump is well constructed, has an amazing and accurate gauge, and I love the release button on back of the valve, to really dial in your pressure needs. I'm not sure how I ever pumped up mountain bike tires before hand, my pressure must have been all over the place.

    Get pumped

    • Familiarity: I've put it through the wringer

    If your garage is full of mountain bikes, make room for the Chamber HV pump. Gone are my days of guesstimating pressure around the 20PSI line. The Chambers massive dial, and individual PSI marks make setting exact pressures a cinch. If there was any flaw in the pump, its that the dial going up to 50 PSI was too much, they could have easily stopped at 30-35 PSI for modern mountain tires, even that might be on the high end. The unit as a whole is solid and stable. The metal base keeps it upright without issue, and the hose is plenty long, and has a good clip to keep it wrapped around the pump when not in use. I can easily reach valve stems with my bike in the stand. The machined handle is bolted on with the same 31.6 clamp of a handlebar. In the future maybe I'll put some cut down bars and grips on it for a personal touch.

    For me this pump was a luxury, could I have lived without it? Probably but really getting the pressure spot on is really very nice. The gauge is nice and big, super easy to read. The pump action was very smooth and easy to pump. It's one of those things that now that I own one I couldn't live without.

    Modern Volume and Resolution

    Traditional floor pumps hail back to the days of 6-day races in the velodrome and rock-hard tubular tires. Most of them have skinny barrels and gauges that go up to astronomical pressures that no one approaches anymore. 170 psi? I can't even imagine putting that much air in a tire! The Mountain bikes in my stable have tires 2.4 inches wide or bigger, , and will never see pressures greater than 20 psi. The Blackburn Chamber HV Floor Pump is higher volume, with a gauge that reads to 50 psi, so it inflates big tires fast, and reads much more accurately than most pumps that are made for skinny tires and high pressures. I can put 17 psi in my tires andgo for a ride, and if they're too firm I'll dial it back to 15 psi next time! The wide knurled aluminum pump handles are a nice touch, and the gauge has the single-pound increments that plus-and-fat-bike riders need. I would say that Blackburn didn't go far enough with the 50-pound gauge--they could have made a big gauge that only went to 25 or 30 psi. I'll hold on to my old pump for road tires, but or everything knobby, the Blackburn chamber HV is my go-to!

    FYI pinkbike's tests show some inaccuracy at lower PSI ratings (e.g. 15ish):
