The Topeak Mountain Digital 2Stage allows you to choose between two pumping techniques. With Stage 1 High Volume, you deliver a high pump volume of 84cc per stroke. This version is excellent for inflating tires up to 30 psi (approximately 2 bar). For higher pressure, the pump can be switched to Stage 2 High Pressure with a simple twist. Although this option has a lower volume per stroke, it achieves a pressure of up to 300 psi / 20.7 bar – ideal for filling forks and shock absorbers. The easily readable digital manometer keeps you informed about the current pressure. An integrated pressure release button allows for fine pressure adjustments. The pump head can be changed from Schrader (AV) to Presta (SV) by removing the front adapter. The flexible and rotatable pump hose relieves the valve stem while pumping. **Features** - Bicycle pump and shock pump in one - 2Stage technology allows switching from High Volume (Stage 1 HV) for tires to High Pressure (Stage 2 HP) for shock absorbers and forks with a simple twist - Digital manometer 300 psi / 20.7 bar - Pressure release button for fine pressure adjustment - Suitable for Schrader (AV) and Presta valves (SV) – the pressure must be released via the pressure release button to remove the front adapter - Rotatable, flexible pump hose - Air pressure: **Stage 1-HV** up to 30 psi (2.07 bar) / **Stage 2-HP** up to 300 psi (20.7 bar) - Volume per stroke: **Stage 1-HV** = 84 cc / **Stage 2-HP** = 11.2 cc - Dimensions: 26 x 4.7 x 3.5 cm - Weight: 210 g **Scope of delivery** - Topeak Mountain Digital 2Stage bike pump and shock pump - Including 1 x CR2032 battery
