Permanent fix to prevent fender slipping?

https://www.amazon.com/SKS-Fender-700...s+fenders+700c



As you can see, where the front fender is attached at the brake bolt, the hole is oval rather than round. To fit my situation, I need the fender pushed up as far as it can go. This means that the brake bolt will be passing through the lowermost part of the oval hole. Gravity and vibration being what they are, I figure it's just a matter of time until the fender slips down.

I'm looking for a permanent way to prevent this slippage by blocking the top 2/3 of that ovalized hole. No dremel to cut a customized insert, so looking for an off-the-shelf kind of fix.

You guys are so ingenious, I know somebody has a great idea! Thank you.

I'd just washers both sides of the bracket , maybe star washers. I drop of locktite there as well

Or if there is enough bracket that you could bend it 90 degrees above the bolt

I use locktite everywhere I can on fenders & racks

Velo Orange sells a mount that allows adjustment at that point but I don't believe you need it

its more for adjusting for large gaps between fender & tire, but it may give you some ideas

cheers

Bend the tab back so the top of it catches on your bolt head.

This should work great. And Retrogrouch says the same thing. Why didn't I think of this? Amazing. Thanks!

Bending the tab is a good idea, but IMO, if the brake mounting bolt/nut is torqued properly, it won't come loose and the fender won't droop either.

You may well be right, but I'll just feel better knowing that it CANNOT slip-- you know how that goes . . .

Like the others said, bend the top of the tab.

I use a Sheldon's Fender nut in this spot so I can keep the fender mounting independent of the brake bolt.
