What about my philips, torx, chainbreaker...?

It's always a struggle to decide whether more functions should be added. We've considered adding more tools and functions, but this first iteration will deliver the core innovation with a simple presentation.

This is pretty expensive for just an Allen key set.

This is not just an Allen key set. What you are getting for the price is an individually machined, hand-assembled, all-metal, rustproof tool that is first of its kind.

How strong is TeleHex?

TeleHex is more than strong enough to withstand torques commonly experienced by 3, 4, 5, and 6mm bolts on your bicycle. 3+4mm sizes were tested up to 12Nm and 5+6mm sizes up to 15Nm. Most adjustments on your handlebars and seatposts don't recommend going past 6Nm


We ship internationally! Shipping times depend on your geography. Here is a guideline: USA – 2 weeks Canada – 3 weeks Europe – 4 weeks Australia – 5 weeks

Who are you?

TeleHex is a small company based in Toronto, Canada. The product is the brainchild of Peter Wen, a Canadian engineering student. He combined his passion for cycling with his mechanical design skills to design, test, and prototype the world's first self-adjusting hex key that actually works. He launched the product in a Kickstarter campaign in 2015 with the help of the Hatchery from the University of Toronto, and aspires to put TeleHex in the saddle bags of cyclists around the world.
