Gem Floor Pump

The Crankbrothers Gem Floor Pump is a solid value floor pump, especially for mountain bike and general bike use. Its best feature is the foot-activated high-volume / high-pressure switch, which lets you move air quickly for bigger tires, then switch to easier high-pressure pumping as resistance builds.

Works well. Durable quality. Will see how well it lasts over time but pleased with initial use and impression.

Like all Crankbrothers products this doesn't disappoint. The dual action is nice too. The high volume is kinda stiff when using, but after you use a bit it smooths out and is very nice. Kinda nice to look and see a aluminum pump stantion.
