The 12 1/4in hex bits are held magnetically in the case, the ratchet is clipped in, and the 60mm extender has an elasticated sleeve to secure it. The ratchet has a fine action with a click roughly every six degrees of rotation. This helps it to turn in tight spaces. The steel ratchet handle weighs 71g, and the complete kit 209g. The bits included will work with most modern fixings, but you have the option to easily customise which bits you take with you to suit your own bike's setup.
