Bolting cycle wings
Does anyone have any pics of how they have bolted their cycle wings to the brackets and how they are made S/IVA safe?
I know alot of people sikaflex theirs on but i am planning to put a bolt through each end aswell just to keep it on 
How long can i resist the temptation to drop a V8 in?

I don't have a picture - but I used stainless steel button-head hex screws. Nice and smooth, so should be IVA-proof.
I'll take a picture if needed.

attach a band of ally to the wing stays in an arc that follows the contours of the wheel arch then silkaflex this way you are maximising adhesion
you also reduce the potential for starring the fibreglas when stones are kicked up as they will hit the ally not the fibreglass
Life is like a bowl of fruit, funny how all the weird looking ones are left alone

Found a picture on my website...
The wingstay itself is threaded and screws go into that (no nuts or sticking-out screw to tear at the tyre).
The wing is also PU'd to the stay - belt AND braces!

Exactly as David has done, drill and tap the flat section of the wing stay and then use dome head socket caps to secure + PU adhesive.
Always check (and trim if necessary) the socket caps to make sure the tyre isn't going to foul on them - it'll eat the tyre quite quick

have you ever removed cycle wings that have been sikaflexed on?
you soon realize why bolts aren't needed

I used a domed-head coach bolt from B+Q.
Had to cut it down a bit and had to file the hole in the cycle wing square but otherwise no drama.

No but i have read too many 'my wing has come off at 70mph' posts.
Thanks for all the replys, i have some domed screws in the garage so can use them

Extended mounting strip, single 6mm countersunk screw with countersunk ally washer on each stay, but very light ABS wings.

I used roofing bolts from B&Q. No problem with SVA

Ditto - I had some on a Westfield that were stuck on with Tigerseal (I think that's what it was called) and they couldn't be pulled off.
With my Locost, I used Wurth adhesive on my first cycle wings and it "lost adhesion" quite quickly. Now they are fixed with stainless dome
headed M8 bolts and nylocs - only 2 bolts per wing. The top of the stays are drilled with slightly bigger holes (10mm from memory) to allow a bit of
give. No probs so far.
