With the 942, we’ve retained the 41mm outer/35mm inner widths of our 941 rim, 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 (2.5mm on 935) 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 942 nets a 30% increase in impact strength yet a 7.5% decrease in weight, compared to our previous rims.
The 942 rims are ideal for the ultra low pressures (10-18 psi) that we like to run with 2.8 Plus tires (or 18-25psi for 2.25" - 2.5" tires). Running any of our 35mm internal width rims work incredibly well with the new 2.8 Plus rubber we've been riding from Schwalbe and Maxxis. The low system weight of the wheels with these rims and tires combined with the monstrous traction advantage have been a revelation for those who have ridden them. We've also had great luck with the new breed of 2.6" tires on the rims, and we think 2.6" is going to be the new tire size of choice for bikes that are compatible.
These carbon wheels include the latest generation of Ibis hubs, featuring a 36t 4 pawl ratchet for a 10º engagement. They are equipped with Enduro bearings and come with either Shimano or SRAM XD drivers.- 29" with 41mm outer width, 35mm inner
