摘要：A suspension device employed between the rear wheel and the frame of a mountain bike. A lever arm pivoted to the frame carries the rear wheel at one end and the suspension device at the other. The rear wheel portion of the lever arm is about four times as long as is the suspension device portion. The suspension device includes a hollow elongated elastomeric spring carrying an aluminum telescoping portion. The telescoping portion supports the elastomer while allowing reciprocating movement along a major axis, but not allowing any rotational movement around that same axis.pornograph
