Abstract

The present invention is directed to a mountain bike frame (10) for use with a rear wheel (118). The frame is a 'diamond-type' frame that includes seat stay tubes (32, 34). The seat stay tubes (32, 34) are spaced apart to define a gap (G) distance between the inner surface of the seat stay tubes (32, 34) at a tire intersection point (P) that at a minimum is greater than about 2 inches. In addition, the seat stay tubes (32, 34) have a modulus of elasticity value and a moment of inertia value such that the modulus of elasticity value (E) multiplied times the moment of inertia (I) value is between about 1.0 lb x square inches (psi) and about 10 lb x square inches (psi). The frame is for use with only a rear disc brake (122) mounted to one of the seat stay tubes (32, 34).
