What is a 29er?
Good question. At the most basic level, a ?29er? refers to a mountain bike with a larger rim than a ?traditional or regular? mountain bike.

The ?29? is actually a bit of a misnomer, as it refers to the approximate diameter of the entire wheel (with a tire mounted), whereas a regular mtb is approximately 26? in diameter.

To be more specific about rim size, the 29er uses rims of the exact diameter of a ?regular?

road bike rim also referred to as ?700c.?
