Front cycle wing

[Se7enBTCC]

Evening,

My near side front cycle wing flew off on track recently, I have a replacement but can someone point me in the direction on how to install the thing, it's on a 2022 Academy Car, looks a combination of some kind of glue and rivet?

Thanks

Please can you add some photos of the bits.

The modern approach is to severely roughen up the wing stays and the underside of the wing where it will fix and use lots of silicone adhesive (Tigerseal, Sikaflex - someone more experienced will be along for the right Sikaflex compound).

I suggest you roughen up a good 25<30mm either side of the stay so there is plenty of adhesion.  Be generous with the silicone.

if you're going for adhesive only there's a list of precautions. But is that the case?

Mine are adhesive only. There was just insufficient between stay & wing first time.

This is the adhesive that CC use and sell,   Very expensive from CC though. 

I bought that exact brand for $25 AUD out here.  I had to remove one of my guards and i can tell you it wasn't going to ever fall off on it's own!

There is a flat plate you can bond to the wing then thread a zip tie through it and it makes your wing removable.

Big Head fasteners.

Don't use normal silicone, it fails ...

Why not just use 4 bolts?

Here's the current approach recommended by CC that I used on my car : Link

Thanks all, I'll give it a go.

Are you going for adhesive, no BigHeads, no bolts? if so there's a few more tips...

"Here's the current approach recommended by CC that I used on my car : Link"

That's good on preparation, and I suspect that poor preparation causes more failures than anything else.

I would add:

1 Sandwich or sausage roll. I prepared the entire surface of the stay, not only the top. I then applied a sausage roll in one step, rather than a sandwich and then a sausage roll. This is because the likely failure mode is peeling at an interface, and this way there are fewer interfaces.

2 Choice of adhesive. Lots of suggestions in the archives, eg from 2021. "There are probably more recommendations in the archives for Sikaflex 221 and Tiger Seal than for anything else. "

3 Make sure that all of the bits are warm.
