Crankbrothers Gem Floor Pump

The high-volume mode allows you to move a large amount of air quickly, which is ideal for seating tubeless tires or inflating high-volume mountain bike tires. The high-pressure mode makes it easier to reach the higher PSI requirements needed for road bike tires without excessive physical effort.

Yes, the pump features a dual-head design that accommodates both Presta and Schrader valves without needing to change internal parts.

The integrated analog gauge is positioned at the base of the pump, which is standard for floor pumps. While you will need to look down to check your pressure, the clear markings make it easy to monitor your PSI as you inflate.

Yes, the pump includes hidden adapters, such as a needle and plastic valve, which allow you to inflate sports balls or other inflatables.

The pump is designed with a wide stamped steel base, which provides a solid, planted feel on the floor and prevents the pump from tipping over while you are inflating your tires.

The Crankbrothers Gem Floor Pump is backed by a 5-year warranty, covering defects in materials and workmanship.
