With the 742, we’ve retained the 41mm outer/35mm inner widths of our 741 rims, while increasing impact strength, reducing weight and maintaining all-important lateral stiffness.
This carbon rim design features a lower cross section height for increased impact performance. The lower 19.5mm section height makes the wheel better able to distribute the loads of localized impacts from rock strikes or hard landings.
Also, we are introducing a new hybrid carbon fiber layup, strategically combining layers of a new, high-toughness carbon/epoxy prepreg with our original carbon composite, increasing both ultimate strength and impact durability. This, combined with the asymmetric rim design that features 5mm of offset, allows for higher spoke tensions that are nearly equal from one side of the wheel to the other. As a result of all this, the 742 nets a 30% increase in impact strength yet a 7.5% decrease in weight, compared to our previous rims.- 27.5" Rim diameter
