between an O-ring & X-ring chain?
One's got O-rings, the other has X-rings....simples!
O-rings have a circular cross-section, X-rings have a cruciform cross-section (looks like an X), they both do the same job of keeping lubricating grease within the chain rollers, the idea of X-rings is that they have a smaller surface area in contact with the side plates and links so there's less friction as the links rotate around sprockets - check the chain manufacturers' websites for their blurb on it....
Make your own choice. In theory the X ring should allow the built in lubrication to last longer but IMHO having used both and as a Scottoiler fan I never noticed any difference, however Gold coloured ones look pretty
nah, just another marketing ploy...................Originally Posted by Squashed_Fly
I always use X-ring chains. In theory they are better and come at no real greater costs
Well if they are gold, then that settles it for me!
Not ACTUAL gold you knowOriginally Posted by Squashed_Fly
;D
Ah what? never!
I thought I could send it off to Cash My Gold when it started to wear out
They are both rubber sealing rings. One has a round section (the o-ring), the other has an X section (the.. oh go, on, you know). Both seal in the same way & last about as long as each other. The x-ring is just a gimmick. I've worked as a design engineer in hydraulics for the last 20 years & I've never seen an X-ring used anywhere. Engineers alway go for the good old o-ring. They are the cheapest & best.
