The fork on the Vertex looks to have collapsed, and may or may not take work to sort, I'm no expert on forks though I'm afraid. The Man 5 I think is original spec for the 6.0, and is a good fork. I'm just changing mine on the 4.0 to Pace RC35s from Indy S
It does appear that the Vertex has non matching rims, but again this may not be an issue. I folded the front wheel on my 4.0 landing a 6' drop off. Admittedly I did this drop off every day for 5 months before the front wheel collapsed on me. It resulted in a dislocated shoulder and new skin, helmet and clothes. The frame is still going strong though.
I think the Axis is 94, the WCF Vertex 95 and the WCF 6.0 96
The Axis didn't come with Gripshit though, so you'd need to get the M737/8? lever combo.
I've also noticed that they don't seem to all be the same size, so that may be an issue. The Vertex looks smaller, maybe 17", the 6.0 looks to be around 19", and the same for the Axis. Maybe wrong on sizes, but the Vertex is smaller
