I've just spent a long time trying to find answers to my questions on previous posts, so I apologize if this has been answered and I missed it.

I am trying to install PB Cascadia fenders on my specialized rockhopper mountain bike. The rear fender I was able to find some holes drilled into the frame that I could mount the stays to. There was no chainstay bridge, so I just used one zip tie through the hole in the fender and wrapped it around the seat tube. Is one enough?

Then front is being more difficult. I have a manitou splice suspension fork, which has a backward-curved fork brace (if I have the name right) so that it is too far back to be used as-is for the mount attached to the top of the fender. I saw in another thread that someon had drilled four holes in the fender, and then looped two zip ties through these to attach to the fork brace. While this seems like it should hold, I'd have to locate a drill, so I'd like to know if there is another solution that does not require that much work.

People have also mentioned using zip ties to tie the stays to the fork. I tried this, but the stays still slide around. The way I have it is the stays run along the side of the fork, to about its midpoint. I've wrapped duct tape around the fork to prevent scratching. Does it work better if the stays are attached just to the back of it (i.e. closest to me if I'm on my bike)? Or do P-clamps work better? I could only find very small p-clamps at my hardware store, do they come in 1.5" diameter (5" circumference)?

Finally, how much clearance should I leave between the fender and the tire, and between the bottom of the front fender and the ground?

Arghhh
