How many o-rings?

[rycell35]

Since this is the first time i have taken the time to actually work on a bike rather than run it into the ground... sell it... and then buy a new one a year or two later i have to ask the really stupid questions.

The o-ring is the piece of plastic/rubber on the side of each link?
How many o-rings need to fall off before i replace the chain?

If you're listening. Your chain has failed as soon as you suspect O-Ring failure. Any traces of red on the chain, any rust, replace it.

I know it is unlikely to happen with modern kit but i had a friend who almost lost his foot when his chain snapped. Apart from tyres it's the most improtant part of your bike (who needs brakes anyway...)..

Well that's my two penneth..

Don't f**k around with your chain too much. If it decides to let go, it can do some real damage..... to your motor, to your leg/foot, to your back, to your passenger, to the car behind you....... It's important. Listen for strange noise, clean and lube constantly, check for stretch on a regular basis.........

O-rings maintain the internal lube for the chain rollers. Heavy lubing will compensate for a while, but it's just a band-aid over a serious problem. The real question is why the O-ring failed in the first place -- lack of lube, too much debris, too much heat, or exposure to chemicals you shouldn't have gotten close to your chain.

KNOW THIS:
Chains and sprockets wear together. Replacing one without replacing the others will cause everything to wear to the same levels as what you just took off the bike in very fast order.
