Future of Road Tubeless from Mavic

Several years ago, coming from mtb, I didn’t really know what my friend was talking about when he said that he chose to go with clinchers instead of tubies. At the time, I was still running tubes, not knowing of other options. Today, I’m running tubeless on mtb, hoping to run tubular for cx, and still in tubes for road.

But I may not be hoping for tubulars for much longer. In US 2015/0028660, published on January  29, 2105, Mavic  discloses a new rim that “is as lightweight as a tubular tire wheel and as practical as an open pneumatic tire wheel.”

As shown above in FIG. 2, the bead 6 of the tire 2 includes portions that fit into the hook 35 and stop 37 as shown below in FIGs. 6a-6g.

As shown below in FIG. 5, the balance of the forces on the hook 35 and the stop 37 allow the rim and tire combination to withstand pressures of up to 10 bar (~145 psi).

Moreover, the design of the rim helps decrease pinch flatting. Shown below in FIG. 7, the base 36 of the rim helps to distribute the forces from impacts in more areas than just the flanges 32 of the sidewalls 33.

These features are also intended to be applicable to mountain biking. I hope this technology comes fast so I don’t have to learn how to glue tubulars.
