Sumart Mini Shock & Tire Pump – Dual Mode High Pressure/High Volume

Sumart AMP-254 Mini Tire & Shock Pump

Compact, high-pressure inflation for tires and suspension in one trail-ready pump.

The Sumart AMP-254 Mini Tire & Shock Pump is a compact, high-performance inflation tool designed for riders who want one pump that can handle both tire inflation and suspension shock setup. With switchable High Volume (HV) and High Pressure (HP) modes, the AMP-254 is built to cover everything from tubeless mountain bike tires to air shocks and forks. Its lightweight aluminum construction, ergonomic handle, and micro-adjust function make it a practical choice for riders who need accurate pressure control at home, in the shop, or on the trail.

For suspension tuning, precision matters. The AMP-254 features a 1–2 PSI micro-adjust button that helps fine-tune pressure without overshooting your target. That makes it easier to dial in fork and shock setup for rider weight, terrain, and ride feel. When switched to high-volume mode, the pump is also capable of moving more air for faster tire inflation, making it useful for everyday riding, race-day prep, and trail-side adjustments.

Key Features & Benefits

• Dual HV / HP Functionality: Switch between High Volume mode for tires and High Pressure mode for suspension components, giving you one compact pump for multiple inflation tasks.
• Up to 300 PSI: High-pressure capability makes it suitable for rear shocks, suspension forks, and other applications where accurate high PSI inflation is required.
• Micro-Adjust Pressure Button: Fine-tune pressure in small increments for more precise suspension setup and better ride consistency.
• Compact 10-Inch Length: Easy to carry in a pack, toolbox, or vehicle without taking up unnecessary space.
• Lightweight Aluminum Barrel: Durable construction helps keep overall weight down while maintaining strength for repeated use.
• Ergonomic Soft-Touch Handle: Designed for a more secure and comfortable grip during inflation.
• Versatile Trail and Shop Use: Useful for mountain bikes, gravel bikes, road bikes, and any setup requiring compact tire and shock inflation capability.

Presta Valve Compatibility Note

The AMP-254 includes a Presta valve adapter for broad bike compatibility. However, if your Presta valve uses a removable valve core, this style of adapter may not be ideal. Because it threads directly onto the valve, removing the adapter can sometimes loosen or unthread the core itself. For best results, use it with non-removable Presta valve cores or take extra care when removing the adapter.

Why This Pump Stands Out

Many compact bike pumps are optimized for either tire inflation or suspension pressure, but not both. The Sumart AMP-254 is designed to bridge that gap by combining high-volume bike pump capability with high-pressure shock pump performance in one portable package. That makes it a smart option for riders who want fewer tools, less bulk, and more flexibility when traveling, racing, or heading out for long rides.
