Significance
The selection between 26-inch and 29-inch tires can mean big differences for serious riders. Endurance athletes who want to maintain speed throughout the course often choose a larger-diameter tire, while short-distance racers are able to be more explosive in their acceleration and reactive with smaller tires.
Function
Velo News reports 29-inch tires are better for cross-country events, make ascending rolling hills easier and descending steep hills safer. In contrast, 26-inch tires are better for longer hills insomuch they are lighter.
Personal Choice
Mountain bikers who are more concerned with fun than fast times can choose a bike on its own merit, its components and the price tag.
Expert Insight
For those who take their bikes to explore other countries, 26-inch tires are more common. Don't expect a small shop in the middle of the Vietnam countryside to carry two-niners.
Considerations
A key factor for any mountain biker is his own stature. For males, if you are 6 foot tall or above, a 26-inch bike might be too small. A bigger bike will not only be more comfortable but will also allow you to accurately adjust your positioning to maximize output and prevent injury.
