Is 2025 the Beginning of the End for 29" Bikes?

32" x 2.4" Maxxis Aspen XC tires have been spotted on a DirtySixer 32er gravel bike, sparking curiosity about the future of larger wheel diameters in the mountain bike industry. Photos surfaced on DirtySixer’s Instagram last week—could this be new trend that the industry wants to sell us? Is your 29er old fashioned already?

The 32" Maxxis Aspen could mark a turning point for XC racing, the only category along downhill without wheel circumference limitations. Travis Brown, a former professional XC racer turned product developer for Trek, he highlighted how larger wheels maintain speed over rough terrain while offering improved climbing, braking, and cornering traction thanks to a bigger contact patch.

However, a key drawback is slower acceleration after losing momentum compared to smaller wheels. A.k.a physics.
