All the great features of the Mountain X with the added precision of a 3.5" LED digital gauge and Topeak's TurboHead pump head. Huge 722cc stroke volume from an over-sized steel barrel inflates high volume tyres nearly 50% faster than normal floor pumps. Topeak's TurboHead pump head delivers high airflow for Presta valves. With an easy on-off design, there's no loss of pressure when removing the head after inflation.
