I drove more than 10 years a Selle Royal Viper on my trekking everyday bike. This article is now sitting as a twin brother of a new on my second bike. The saddle is not related from the Group board, but entirely upholstered in a reasonable extent, I feel that as a very pleasant even during long and sporty driving. Because he has the same time so much resistance that the power goes into the pedals and is not swallowed up by too much damping. I find this solution to be extremely optimal. In addition, the saddle looks good (I know taste is very personal) is relatively easy and the price very reasonable. Strong buy recommendation for sporty everyday rider.
