928 Carbon Fiber 29in Wheelset - DT Swiss 350 Rear Hub

Given the fact that even skinny road wheels are getting wider with each new generation, it's hard to argue against them on mountain bikes. The Ibis 928 29in Wheelset continues its efforts to establish a new standard with its 28-millimeter width, and the addition of a DT Swiss 350 Rear Hub means the 928s are some of the most race-ready factory-built wheels that we carry.

The wider rim's largest benefit may be felt in tire pressure. They're tubeless-ready and, with a wider footprint, allow the tire's sidewalls to stay vertical rather than swelling like a light bulb. Both of these mean you can run lower pressure without sacrificing efficiency or risking a burp — in fact, they actually grip better while cornering and offer improved power transfer through a more efficient contact patch. Ibis has found that light riders on moderate terrain can run as low as 17psi in the 928 rims.

The generous width also makes the rims themselves more structurally sound, even while using less material. The profile design of the rim is essentially a rectangle, not an inverted "T." This spreads out any impact force over a greater area, especially when partnered with Ibis' hook-less bead. The result is less weight, more stiffness, and a stronger overall rim.
