OK, I called and talk to Kim, she told me that at the moment they are not interested in a group buy because they have to much work. They probably will have one for all bikes at the end of October or starting November. I will call her back because I am waiting for this. She said we can save from 10% to 20% depending in the number of orders. I hope this help the people interested, to make a decition on buying now or later.
