You tool nerds have certainly noticed this crafty little driver. The 826 T Kraftform Turbo bit-holding screwdriver handle with Rapidaptor quick-release chuck takes all 1/4" x 146 mm hex bits.
Thanks to a purely mechanical gearbox in the handle it allows on-and-off fixed gear and X4 speed—a pure bicycle design vision. Bicycles saw the world's first mechanical gear boxes and this is a direct descendent. It will delight your work, accelerate your lacing, and entertain customers and friends.
Note: the tool is green and black and the nipple driving bit shown is not included.
