The rack seem sturdy and nice and so does the read fender.
The front fender is not really compatible with anything that Biktrix sell (neither the Renegate or Wren fork). You can try your luck and mount it with only one screw where the light goes on the Renegate, but the thing only lasted one week before the mount broke straight off even tho it's made of metal (Chineseum to be precise).
Edit to answer from Biktrix: that disclaimer is stupid if it's not compatible with anything you sell for this bike.. why even include it in the box. What is it even compatible with? Another bike..
Edit 2: They confirmed by email that the front fender won't work at all with this bike so don't get your hope up that you finally found a compatible one for this bike, it will go to the trash the second you get it. I still think the rack is worth it at this price tho.
