You are bidding on a new Arione R3 saddle, it was part of the build kit that came with my Giant Propel, I used a wider saddle I already had so it was never installed or used.

Specifications:
Arione R3: the Arione is longer than any other saddle, flat from nose to tail and with a narrow nose, so you can move around to find your power spot.

The Arione R3’s Composite Glass co-injected Nylon shell provides the best support with optimized stiffness to-weight construction – with Wing Flex technology which enables flexibility where the rider's thighs meet the saddle – and an alloy K:ium rail for light weight.
