Bicycles occasionally require adjustments and repairs at inopportune times. The most portable solution is to carry a fold-up hex set to address the most common breakdowns. However, this tool is unnecessarily bulky, and selecting the right size can be tricky and frustrating especially with gloves. The TeleHex mechanical unit will condense the most common hex sizes into one unit, reducing volume by up to a factor of 4, weight by a factor of 3, making it portable enough to carry on a key chain. It will allow the selection of the correct sized hex on the first attempt.
