The biggest selling point for a non-o-ring chain is they are much more efficient. There are some very high quality plain drive chains available and in conditions where they are cleaned and lubricated they last as long as an "O" ring chain and they have some advantages.

A plain chain drive is unique because it is the most efficient mechanical drive system known and they typically transmit around 97% of the available power which is well above belts, straight-cut gears, bevel gears or drive shafts with pinions or even "O" ring chains.

An O ring chain is less efficient because there is high friction on every single link from the compression of the rubber ring and there is a large power loss especially with smaller sprockets when the chain is new. It's easy to feel the difference of the rolling resistance of a plain link chain by rolling the bike.

That's mainly the reason that race bikes, and MX bikes and other high performance chain systems use plain roller chain. Along with the fact they can be changed in minutes without even jacking the bike up or using any special tools.

Having a problem with an endless riveted chain, is often an impossible trail-fix. The advantage of a plain chain is the chain can be replaced in minutes more frequently and that means more power and sprockets last longer.

But, you do have to clean and oil them more frequently.

When I replaced my chain a couple of months ago I did not go with the O-ring chain but chose a high quality standard DID Chain. I ran a non O-ring on all of my race bikes without problem for YEARS so made the decision that worked for me. I do clean and lube regularly! I am in patuca's camp, good post! Different strokes for different folks.

I also think O-Ring versus standard depends too on riding conditions. If you're in water, sand, silt, dust & mud an O-Ring chain will keep contaminants out of the roller surfaces. Extending chain life. I hate to admit it but I never clean or oil chains. Lazy perhaps.

No doubt the price paid for the O-Rings is increased friction and a slight loss of power transmitted to the rear sprocket. That may or may not matter to a specific rider. It doesn't to me given we ride mostly trails and average 10 MPH. Many of the roads/trails we're on have mud, silt and dust. Best to keep such things out of running surfaces.

Yes different strokes for different folks. Just my 2 cents worth.

I fit X ring DID chain on mine with split link.

I used to run unsealed chains on my old '79 DT175MX, some tried the (new to us at the time) O ring chains, they were 3 times the price & lasted 4 mebbe 5 times as long. So financially the better option, but when we had so little bhp, some didn't want to lose a half of one due to extra resistance. They did get a hard life back then being used purely for off-roading in mud & crud.

The unsealed chains do wear out quick, wearing out the sprockets while they're at it. Need replacing as a kit.
