PS 1.1 GRX one layer of yellow tapeSimilar in design to the PS 1. 0, it features the same sloped front arms, but slightly thicker 30 series padding, and budget friendly chromoly rails. Similar to the other Performance Short saddles, the PS 1. 1 features an upward slope at the rear providing superb hip support when your body is rotated forward in the aero position, or an aggressive road riding position. This tends to be preferred by athletes that don't move around on the seat
