Few tools are used as frequently, and can cause as much heartache or wasted time as the seemingly simple hex key. It’s one of the first things you notice at the top levels of motorsport tools, or in the toolboxes of Pro-Tour mechanics: extremely high quality hex keys.
Included with the HX-One Essentials Kit is the proprietary SILCA 17-4 Stainless Magnetic Adapter. The Adapter with a pleasant magnetic click turns the 6mm Hex Key into a ¼” socket drive which can fit any common ¼” driver Bit. Included in the kit are the 6 most common Torx sizes, 2 Phillips Head and 2 Flat head Drivers. You can literally handle any modern bicycle fastener with the tools in the box.
