Horchata, also known as orxata, is a sweet drink popular in Latin America, Spain, and parts of Africa. The drink is rice-based in Latin America, but in Spain and Africa it is made with tiger nuts (chufa). A traditional recipe always calls for cinnamon and water, but beyond that, there are hundreds of variations.
The bigger wheels, however, have been skulking around the scene for decades. In 1999, Wilderness Trail Bikes got the ball rolling in earnest when they produced the first real 29er mountain bike tire. Soon riders began touting the benefits of the bigger wheel size. And those benefits are undeniable. For starters, the big wheels roll over obstacles with greater ease than standard 26-inch wheels.
If you are interested, here is the link to Sheldon Brown's article on tire sizing. The point is that a mountain bike 26 inch wheel has a smaller diameter than a 700c racing wheel. That means smaller circumference, so more rotations of the wheel in a given distance. This means more tire wear. My cycle computer manual gives the circumference of the 26x1.25 tire that I have on the bike as 195 cm.
