Instead of a standard O-ring, this Silca offering has an adaptable seal cup which reacts to increasing temperatures for a more efficient inflation experience than other pumps using Os. The integrated heat sink at the end of the barrel works to absorb the majority of the heat emitted during pumping to keep the pump cool at all times, while the twin tube insulated handle gives an insulated grip when thrusting away. Constructed of a 6061 alloy construction, the barrel and gripping surfaces are durable and lightweight, making it a perfectly pocket-sized and carriable inflator.

Utilising the iGauge mobile app to get those readings, the Tattico Bluetooth Mini-Pump w/ Mount will make sure your tyres get back to within 0.5psi accuracy with every use. Capable of inflating up to 120psi, this manual inflator is the first Silca portable pump in over half a century to feature an in-built hose. Housed inside the inner barrel, it slides in and out of the pump with ease, with no need to remove it, making for a seamless pumping experience and up to 10% more air per stroke than conventional mini-pumps. Presta and Schrader compatible, the compression gasket attaches to the hose and is put to use via a small aluminium lever. The Tattico Bluetooth Mini-Pump also features an adaptable cup seal instead of standard O-rings, which grows with your tube for the highest efficiency in all temperatures, a hidden heat sink that keeps the pump cooled from the heat generated during pumping, and a twin tube insulated handle to keep your hands cool and comfortable as you push and pull.
