Hand Pump Blackburn Mammoth 2-Stage Anyvalve HP/HV up to 120 psi, silver

The Blackburn Mammoth 2-Stage floor pump is a manual inflator designed to serve a wide range of bicycle tyre types. It combines a robust metal barrel finished in silver with an ergonomic handle and a dual-stage pumping mechanism. The Anyvalve head is compatible with both high-pressure (HP) and high-volume (HV) valves, and the pump delivers pressures up to 120 psi, making it suitable for road, gravel, mountain and fatbike tyres. Its construction and valve versatility make it practical for home workshop use and roadside adjustments.

Advantages

The two-stage pump action provides efficient high-volume inflation on the low-pressure stage and precise high-pressure inflation on the high-pressure stage, reducing effort and improving control. The Anyvalve head allows quick switching between Presta and Schrader-style connections without additional adapters. A solid metal barrel and a stable base contribute to durability and steady operation, while the ergonomic handle improves grip and comfort during repeated use.

Suitable for

• Inflating high-pressure road and gravel tyres
• Pumping high-volume MTB and fatbike tyres
• Home workshop tyre maintenance and inflation
• On-the-road top-ups and emergency tyre inflation

Key specifications

• Maximum pressure: up to 120 psi
• Pump type: manual floor pump with two-stage action
• Valve compatibility: Anyvalve head for HP and HV valves (Presta and Schrader compatible)
• Barrel material: metal with silver finish
• Handle: ergonomic design for improved grip
• Use: suitable for a broad range of bicycle tyre volumes and pressures

How to use

Place the pump on a stable surface and position your tyre valve to access the Anyvalve head. Fit the head onto the valve and secure it according to the head’s locking mechanism. Use the low-pressure stage first for large-volume tyres, then switch to the high-pressure stage to reach the target psi for road or hybrid tyres. Monitor pressure using the pump’s gauge if equipped or check tyre firmness manually. Release the head and remove it carefully once inflation is complete to avoid rapid air loss.

Usage recommendations

For optimal performance, inspect the pump and valve head for debris before each use. When inflating high-volume tyres, start with the low-pressure stage to move air quickly, then switch to the high-pressure stage for final pressure. Store the pump in a dry place and avoid dropping it to prolong the life of the barrel and valve head.
