Not a bad price at all for a Ciocc made with SLX. I suspect the Victory group is holding the price down. I personally like the looks of the crank but a lot are turned off by the angular look. Replacement rings for the 116BCD spider can be hard to come by and pricy.
When was the last time you shipped a bike? $160 sounds about right depending on your location. Shipping bikes went up almost 200% in the last 6 or 7 years. you might try talking the seller into using Bike Flights but don't forget the seller also has to schlepp around to find a box and then pack it up or pay to pack it up. Packing and shipping is a real pain in the saddle.
BTW the seller does not seem to have much feedback, some here take a dim view of sellers with low feedback.
