Blackburn has been making innovative cycling accessories since 1975. With high volume, camo and orange colors and steel construction, their Chamber HV floor pump is aimed at mountain bikers through and through.
Blackburn Chamber HV features
- Oversize pump shaft for extra durability
- Pump head features rugged alloy cap and lever
- Super long 47" hose to reach valves in stands or car racks
- Convenient integrated hose keeper on handle
- PSI and Bar increments on gauge, with vibrant color matched background
- 50 PSI, 3.4 Bar maximum
Blackburn Chamber HV inflation time
Squeezing air from one chamber to another can be done in two ways: with big volumes at low pressures, or small volumes at high pressures.
Floor pumps are typically high pressure affairs, often delivering inflation numbers up to 120psi and well beyond, even up to 220 psi. While that covers the gamut from ultra-low pressure fat bike tires to high-zoot track racing tubulars, it doesn't do much in terms of precision. And when half a psi makes a noticeable difference, as with fat bikes or even plus size rubber, that precision is paramount.

Blackburn's Chamber HV floor pump is designed to make every pump count. No really, the steel barrel is oversize to move a larger amount of air into your tire, hence the high volume (HV) part of the name.
It's noticeable, a 29x2.3in wide tire can get between two to three psi with every stroke. Each stroke is harder than a regular floor pump to compress, but it's somewhat reassuring to actually feel in your triceps how much air is being moved, and know much sooner you'll be riding.
