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.
Typically, any 700 tire today is essentially the same size as an old 700c tire. You do see 650b, which is the same as today's 27.5 mountain bike tire, as well as 650c, which has a slightly smaller inner diameter than a 650b tire and is found on a few road bikes.
