This is a lighter weight and superbly supportive Xtreme Reactor Panel, Mono-Flap Endurance Saddle which is based on the Xtreme but with a single flap to cut down on the bulk and reduce the weight by 2kgs.
It is one year old and in perfect condition. It was bought from new for nearly £3000. I am open to offers and will post free of charge to the UK.
Any questions please feel free to ask and I will send additional photos if your wish.
