Professional Suspension Tuning – ACID Pump Race Shock 400
The ACID Pump Race Shock 400 is a precision-engineered shock pump designed for mountain bikers and suspension enthusiasts who demand accuracy and reliability. Whether you’re setting up a new bike, fine-tuning for different trail conditions, or maintaining optimal shock pressure, this pump delivers professional results every time.
Key Features That Make the Difference
2-Stage Head Technology
The innovative two-stage head design for Schrader valves is a game-changer. Unlike standard shock pumps that lose air when you disconnect, this clever engineering prevents air escape during removal, ensuring your carefully set pressure stays exactly where you want it.
High Pressure Capability
Up to 400 PSI With a maximum pressure of 400 PSI (approximately 27.6 bar), this pump handles all modern mountain bike rear shocks and forks from manufacturers like Fox, RockShox, Öhlins, DVO, Marzocchi, and more. Whether you need 50 PSI for a plush setup or 300+ PSI for aggressive riding, the ACID Race Shock 400 has you covered.
Precision Pressure Gauge
The large, easy-to-read pressure gauge provides accurate readings so you can dial in your suspension to manufacturer specifications or your personal preferences. No more guesswork – see exactly what pressure you’re running.
Micro-Adjustment Air Release Valve
Fine-tuning is effortless with the built-in air release valve. Make precise micro-adjustments to find that perfect sweet spot between comfort, traction, and bottom-out resistance. Reduce pressure in small increments without having to start over.
Ergonomic Natural Fit Handle
The Natural Fit handle design reduces hand fatigue during pumping, making it comfortable to reach higher pressures. The ergonomic shape provides excellent grip and control, even with sweaty or gloved hands.
Durable Aluminium Construction
Built with a robust aluminium barrel and quality plastic components, this pump is designed to withstand regular workshop use and the occasional knock in your trail bag. At just 219g, it’s light enough to carry but substantial enough to feel premium.
Why Proper Shock Pressure Matters
Setting correct shock pressure transforms your riding experience. Too little pressure causes harsh bottom-outs and reduced pedaling efficiency. Too much pressure sacrifices traction, comfort, and control. The ACID Race Shock 400 gives you the precision needed to find your optimal setup for different rider weights, riding styles, and terrain types.
