I brought O rings from the local bearing shop & used them,they worked great for about a month then I noticed they were perishing & then in another month they had gone ping & snapped,I figure they are really not meant to be stretched & used under tension only as a seal,or my shops stock is old as the hills,any feedback on this or what you are using,Is there a different type of O ring I should get,I have had this happen a few times on different bikes with different sizes over a couple of years,the original ones are NLA :)

VMX Unlimited are still showing the RM Suzuki-type brackets in stock, so that's the bracket and retaining strap that wraps round the fork leg for $45 a pair, tidy solution.

The rubber in some o-rings seem to have gone the way of everything else these days - crap ! as soon as they hit uv's they will only last a few weeks ,i'd say you would need to go nitrile or viton to get any life outta them in that situation or call les :)

after years of dealing with everything from rubber bands to duct tape to hold my number plates on securely, I now use these neat little gadgets on all of my bikes.

EPDM (ethylene propylene diene monomer (M-class) rubber)
The main properties of EPDM are its outstanding heat, ozone and weather resistance.

Nitrile is useless when exposed to sunlight/UV rays & is the material most off the shelf o-rings are made of

Peg board clips. $2 a packet. Used two or four per plate

Ahh - maybe its viton then ! which are aparently useless on shafts :)

inner tube and ya get all size rubber bands, from pushy tubes to truck and wait there'smore :o
binder twine and rusty wire is all the go a 1000 farmers cant be wrong ;) farmers are outstanding in their field

or these......another version of the ones I use. Seriously chaps, the old rubber band, cable tie, untidy fix is just soooo yesterday. For $32 a pair why bother with anything else unless you're an originality anal or building a rat bike ::).

or if period correctness is your particular fetish, why not try these Preston Petty headlight mounting brackets. How many of us have them laying around attached to a faded or broken old Petty headlight. They often come up on eBay for piss money or if you need new, Strictly Hodaka stocks them for around $30 a set.

I made my own set of alloy mounts based off those ones that Firko put up, work well although I have a front plate that is shattered around the mounting point from something hitting it. They really need to be a bit wider
Anyone tried the round plastic type that get advertised on Mark's swapmeet?
