This clever bike multitool fits perfectly into your otherwise unused axle crank, and it has all the tools you need. It’s available with a cap in one of six mostly bright colors. without the bright cap, you might forget it’s there. You get most of the bits and tools you need, including Allen bits, screwdriver, Torx wrench and slots for backup chain links. Have some other stuff you need? No problem, just pop in whatever bit you need. Because it uses the standard sizing, it is easy to change them out. The design also lets you get plenty of torque to unstick the stuck, which means no struggling. No need to carry anything in a bag, have a custom holder on the frame or start strapping stuff down. It’s always there yet always out of the way. $95 and available now.
