The Modern Tire Lever Problem
The mainstream use of carbon rims and the ever increasing popularity of tubeless means that the wheel systems of today are lighter, faster, more comfortable, and more versatile than they've ever been. While these technologies have addressed the needs and wants of riders, their development mandates advancements from the surrounding systems and those used in conjunction to ensure effective, reliable, and safe use. Nowhere is this cause/effect relationship more evident than in the tools that we use on the different systems of our bikes.
Let's examine tire levers for a minute as they relate to carbon rims and tubeless setups. Deeper rim walls and more robust beads mean that tire fits are now tighter than ever and therefore require more leverage to displace. Yet at the same time, your carbon rims still require solutions that protect the surfaces from damage. The most common carbon safe solution out there are plastic levers. While these protect your rims, their lack of durability is problematic. Plastic tire levers are prone to snapping and so the solution is often to make them thicker. Not only does this add bulk to the tool but it also makes it very difficult to get the blade under the bead. Another common solution to the problems associated with plastic levers has been to insert a metal core into them but this adds stiffness where you don't really need it.
We've spent over a year thinking about these issues, possible solutions out there, and are pleased to introduce Tire Levers Premio.
