Manual Pump Blackburn Mammoth 2-Stage Anyvalve HP HV up to 120 psi black

The Blackburn Mammoth 2-Stage Anyvalve is a manual floor pump designed to serve a wide range of bicycle inflation needs. Its two-stage barrel provides a high-volume mode for quickly inflating wide tires and a high-pressure mode for achieving up to 120 psi for road and performance tyres. The Anyvalve head accepts both Presta and Schrader valves as well as HP/HV fittings, making the pump suitable for mixed fleets or riders who carry a single pump for multiple bikes. The pump is built for home use and roadside repairs, offering a stable base and straightforward pressure control.

Advantages

The two-stage design combines efficient large-volume strokes with a separate high-pressure stage to reach pressures up to 120 psi. The Anyvalve head eliminates the need to swap adapters, supporting Presta and Schrader valves and HP/HV systems. A sturdy base and ergonomic handle provide stable pumping and comfortable operation during extended use. The pump's construction focuses on reliable, repeatable inflation performance for both wide MTB and narrow road tyres.

Suitable for

• Inflating road bike tyres requiring high pressure (up to 120 psi)
• Pumping mountain bike and gravel tyres with high-volume strokes
• Home workshop tyre maintenance and roadside repairs
• Use with bikes that have mixed valve types (Presta, Schrader, HP/HV)

Key specifications

• Two-stage pumping mechanism: high-volume and high-pressure modes
• Maximum pressure: 120 psi
• Valve compatibility: Anyvalve head compatible with Presta and Schrader, supports HP/HV
• Floor pump format with stable base and ergonomic handle
• Suitable for a wide range of tyre sizes from road to MTB

How to use

Place the pump on a firm surface and stabilize the base with your feet. Select the appropriate pumping stage: use the high-volume mode for rapid inflation of larger tyres and switch to the high-pressure mode when approaching the target pressure for narrower tyres. Fit the Anyvalve head onto the valve—presta or schrader—ensuring a secure connection before pumping. Pump until the tyre reaches the desired pressure and carefully remove the head, closing the valve if required. Check tyre pressure with a gauge or the pump’s indicator if present.

Usage recommendations

Regularly inspect the pump head and hose for wear and ensure valve seating is secure to avoid air leaks. For precise pressures on road tyres, switch to the high-pressure stage as you near the target and use a separate pressure gauge if exact values are critical. Store the pump in a dry place to prolong seal and hose life.
