rs スペックダンパー

My friend just installed an rs スペックダンパー on his touring bike to smooth out the ride on rough roads. He says it really dampens those sudden jolts from bumps and potholes, making long days in the saddle much less punishing. I'm thinking about getting one for my own bike, since I often ride on less-than-perfect pavement and could use that extra comfort without sacrificing stability.
