I'm riding a Pipedream Sirius. The build quality is very good and it uses a nice tube set. They are designed around a 65* head angle given a sagged 100mm fork. I've got a 120mm z2 and wouldn't want it much slacker. The stack height is pretty low on that frame, so I think many would end up running spacers or higher rise bars. I bought it from Brian at Smith Creek Cycle in Kelowna - solid dude, nice shop.
