Ibis completes its wheel lineup with four carbon and two aluminum wheels

The new Ibis bike brand's wheel portfolio comprises a total of nine different models. In addition to lots of carbon fiber, the Californians are also offering aluminium rims for the first time. These come with an inner width of 35 millimetres and are available in 27.5 and 29 inches. The carbon rims are also available in both dimensions and from 22 to 35 millimetres internal width.

With the new 742 and 942 rims, Ibis retains the 41 millimeter outer and 35 millimeter inner width of the 741 and 941 models, but increases their impact resistance and reduces their weight at the same time. As the new rim profiles are asymmetrical, the lateral stiffness of the entire wheel is also increased.

Ibis is also proud to announce its two new aluminum wheelsets 738 and 938, whose rims have the same rim width as the carbon rims, but only 38 millimeters on the outside. The rim design is also similar, and so the aluminum rims also have spoke holes offset by five millimetres, are tubeless-ready compatible and have the same spoke tension.

For gentler trail use, Ibis presents the 735 and 935 wheels, which have 35 millimetre carbon rims with a 29 millimetre rim width. They are around 55 grams lighter than the wide 42 mm wheels, but have the same properties as them. Compared to the 928 cross-country wheel with a 28 millimeter rim, the new 935 wheelset weighs just ten grams more, despite the more stable rim and higher wheel stiffness.

Technical details
The new design of the carbon rims includes a deeper rim cross-section for better impact absorption. The forces of impacts from hard landings are thus better distributed over the rim instead of acting on one point, which can damage the rim more quickly.

In addition, Ibis uses a new hybrid layup of the carbon fibers. This combines the layers of a new, highly tough carbon-epoxy prepreg fiber with the original composite material from Ibis. This combination ensures high stiffness as well as impact resistance. Together with the asymmetrical rim design, the rims allow a higher spoke tension that is almost the same on both sides. This makes the Ibis wheel around 30 percent more resistant to impacts, while the wheel is 7.5 percent lighter compared to those with the previous rims.

Hubs
The carbon wheelsets come with high-quality Torch hubs from Industry Nine. These are manufactured in the USA and conceal a 60-tooth ring in the freehub body with six pawls that engage every three degrees. The brake disc mounts are center-lock, the hubs are equipped with robust enduro bearings and are compatible with both Shimano and Sram XD freehub bodies.
The new wheelsets already come with Boost hubs. Ibis will add the conventional hub dimensions of 100 and 142 millimetres if there is sufficient demand. However, the current carbon wheels are still available in these dimensions.

The new Ibis hubs are installed in the current carbon wheels and the aluminum versions. In their freewheels, four pawls engage in a 36-tooth ring - the same for Shimano and Sram bodies. The freehub is also larger to make it more resistant. As a result, the new hubs lasted 20 times longer than their predecessors in the wear test.

The new Ibis wheels are set to hit Swiss specialist retailers between the middle and end of June 2016.
