Leave the CO2 at home. The Elettrico Micro packs the inflation of four-plus CO2 cartridges into a USB-C rechargeable unit about the size of an earbud case, with an auto shut-off that makes it safe for hookless rims.

Highlights

• Equivalent to 4+ CO2 cartridges, with no wasted cartridges
• Auto shut-off at 72 psi, safe for hookless rims (no gauge)
• USB-C rechargeable; a single charge lasts for months
• Carry-on travel safe for destination rides and races
• 111 g and 65 x 46.5 x 28 mm

Using it

Turn the pump on, then double-click the power button to start airflow. The double-click stops it starting by accident in a bag or pocket. It fits in both SILCA Mattone seat packs with room for tools, and in some frame storage (check the dimensions).

Charging and care

Charge time is 25 to 60 minutes. If it needs a reset, charge for at least 10 minutes to prompt a hard reset. It works in hot and cold conditions, but store it somewhere temperature controlled, as extended heat or cold drains the battery faster.

Compatibility & fit

Fits directly onto Presta valves; the included threaded hose works as a Schrader adapter. The threaded Schrader receiver on the gasket cover also accepts SILCA Schradero and Hiro chucks and other threaded chucks, including the CLIK adapter.
