The Odyssey Travel tool was designed to be the only tool you need to dissemble and re-assemble your BMX bike while traveling or for repairs when out riding. This multi tool includes 4,5,6mm hex wrenches, a 17mm deep socket, 15mm / 17mm pedal wrench and an integrated storage compartment. Best of all the Odyssey Travel Tool is big enough to give you the leverage you need when working on your bike, yet small enough for easy transport.
