Hidden CO2 Tire Pump
If you own a higher-end road or mountain bike with a Shimano drivetrain, then chances are it's got a "secret" storage compartment: the hollow space in the axle, that connects the Shimano Hollowtech cranks. While you're not going to be able to fit your phone or wallet in there, you can pop in the new CrankPump CO2 tire pump. It's a portable CO2 pump for road bike tires! The CrankPump Kickstarter is live now. You can check it out at http://www.crankpump.com
