Power rankings: The unexpected findings of comparing 32"versus 29" wheels in the real world
A cycling magazine conducts a real-world performance test comparing 32-inch and 29-inch mountain bike wheels. The findings suggest that the performance gap between the two sizes is less significant than industry speculation implies.
Why it matters
The analysis provides empirical data for consumers navigating marketing claims in the cycling industry.
The promised arrival of 32″ wheels is being accompanied by an endless ream of speculation. From those that know, and those that are guessing. All kinds of technical talk about how much of an advantage the big wheels will be compared to their diminutive predecessors. We’ve talked to pro riders about their own 32″ bikes , we’ve consulted the tire designers responsible for helping create the actual tires for 32″ , we’ve consulted the oracles and looked to the stars to try see the future.
But when the rubber hits the dirt, what are the actual differences between 29″ wheels and 32″? Are they actually faster? Where are they faster? And how much faster?
The findings are not what you’d expect. At least, not entirely.
