OneUp Components EDC Pump offers a unique storage solution integrated into a high-volume pump. It is designed to integrate with the EDC Tool System, CO2 canister, or your favorite stash. Crafted from aluminum with a durable textured machined finish. Pump Volume A mini pump might look appealing, but with typical volumes of 30-60cc it will take hundreds of strokes to inflate a new tube and has absolutely no chance of re-inflating a tubeless setup. When you get a flat, you want to fix it as fast as possible as riding time is precious. At 100cc and at 160g our high-volume pump has the highest volume-to-weight ratio on the market. Fast-On Head Firmly push the pump head onto the Presta valve until it bottoms out, then pump. With OneUps fast-on head the valve stem is securely supported so theres no chance of bending, breaking, or unseating the valve and no chance of unscrewing your valve core when you remove the pump.
