Ibis' new 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.
The 735 is ideal for lighter trail bikes that see more XC time, and also great for riders looking to save as much weight as possible, while taking advantages of the features that wide rims bring you.
Also, Ibis is introducing a new hybrid carbon fiber layup, strategically combining layers of a new, high-toughness carbon/epoxy prepreg with their original carbon composite, increasing both ultimate strength and impact durability. This, combined with the asymmetric rim design that features 2.5mm 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 735 nets a 30% increase in impact strength yet a 7.5% decrease in weight, compared to Ibis previous rims.
