Full length fenders on a fork that's not drilled at the crown

[jever98]

I’d like to fit permanent fenders on a cross disc fork, which has QR drop outs. I can attach the fenders at the drop outs, no problems there.

The snag is that it isn’t drilled at the crown, so I don’t know how to attach it there. I thought maybe there is a way to attach something to the fork crown race?

If possible, I’d like to avoid using something like race blades or Crud Catchers.

Thanks for tips!

Drill 4 holes into the fenders (2 at each side) and attache with zip tie to the fork. It will look something like this: https://i1.wp.com/buckyrides.com/wp-con ... .jpg?ssl=1 (minus the crown attachment).

in my experience, crud catchers are crap but raceblades are pretty decent.

attaching fenders to the dropouts is a nightmare if you have to fix a puncture

P clips at the dropouts.
Anything else is a pain in the arse.

It the bottom of the crown hollow? Or is there a hole in it?

Here some pictures of the fork. I guess I could buy a fork that is drilled, but it would be unpainted - sniff. Drilling it and epoxying a nut in seems dangerous.

Nah, no need to drill. Was actually looking for a hole in the bottom of the crown. A lot of forks have them.
Just drop a penny washer and ~30mm long M4 bolt down, so it sticks out the hole, then use the hole in the guard and another washer/nut to clamp the guard to the crown.

Dependant on you having a bung in the top, not a star washer!

This one unfortuntaly doesnt seem to have a hole there

it'll be bigger p-clips then :/

I still think that drilling the mudguard is the easiest and most effective way. The principle can be seen on these pictures, but instead of the short mudguard, you have the long one.
If you don't want to drill the fender and use cable ties, try glueing some heavy duty velcro at the bottom of the crown and on the fender?
This CX bike has no holes for full fenders, but with some thought and engineering, it has full fenders attached. And you should avoid using QR dropouts!

PS. Try using "rotate" function on your pictures next time

Thats what you need rather than attatching to the drop out. Something like 17-19mm, just above the height on the disc caliper mount. Bend it so it fits tightly/flush. Bit of tape underneath to stop you marking the CF (as they will move/vibrate a bit during use)

An option could be to get some 22mm ones and flatten them out to fit at the top of the legs, then bridge between them/over the tyre, mount the guard to that.

(You can get the same clips much cheaper if you shop around)

+1 on the zip tie suggestion. I've had mudguards zip tied on for decades without problem. Plus it's a lighter way of mounting than any other method.
