Replace whole chainset if replace front chainring?
Hi,
I need to replace my front chainring 'cause it's broke. Will I have to replace my entire chainset? People have told me that the entire chainset stretches with use and so if you replace one component, you have to replace the whole lot. I've probably used my bike for at least 1000 rides. Thanks, Jack PS - this thread is related to my one below asking "Fractured front cog?" |

Put it out to pasture. |

Thanks, Jack PS - this thread is related to my one below asking "Fractured front cog?" Daniel, "Have to...", well, no. But it is certainly recommended. Any component you add to the worn system will wear down more rapidly and will adjust the wear patterns on the old components, forcing them to work less efficiently and wear out as well. Every component on the bike is about the same age and has the same wear. As one component wears down, the rest are forced to wear down similarly. Considering that the front chainring is seriously worn, so are the rest of the components. They probably need replacing anyway or they will faili shortly, probably when you are inconveniently located. Rick |

Hey Jack, Your crankset is the kind that is all riveted together. You can't replace just the inner ring. Your cogs are worn, as others have said. Replacing the whole drive-side arm is a good thing to do. Check your local bike shop for a used parts bin and see if they have any right-hand (drive side) crank bits... you don't need to buy the left side if it's not in need of repair. And as I said before, make sure you can replace individual chainrings on it. -- Phil, Squid-in-Training |

Replace whole chainset if replace front chainring?
Hi Phil,
Sorry, I'm getting my terminology confused again. What I meant to ask is: will I have to replace my entire drive chain (cassette, chain, crank set)? I know I'll have to throw out my right crank arm and chain rings. Thanks, Jack "ZeeExSixAre" wrote in message ...

People have told me that the entire chainset stretches with use and so if you replace one component, you have to replace the whole lot. I've probably used my bike for at least 1000 rides. Assuming its a modern, not lowest end, crankset, then you can just replace the chainrings individually. Chainrings wear a long, long time. Much longer than chains or rear cassettes. On really low end bikes, the crank and chainrings may all be one piece. Along with the bottom bracket too. In that case you would have to replace everything at once. But assuming you bought the bike in the last 10 years and paid over $300 for it, you can replace the chainrings individually. However, it may be cheaper to buy an entire new crankset. Individual chainrings seem to cost about as much as an entire crankset, including both chainrings. |

Thanks, Jack PS - this thread is related to my one below asking "Fractured front cog?" Note that the term "chainset" is usually used to denote left crank, right crank/spider and chainrings. I think you mean should you change the whole drive train. The answer, given the amount of use you have had is probably yes, but this is unrelated to replacing the chainring. On the whole chainrings can be replaced without reference to the rest of the drive train. However, your "1000 rides" will very probably have worn out your chain, which should be replaced when stretched by 1/8" in a foot. If you have not replaced your chain, it is quite likely worn beyond this point, and consequently your rear sprockets will have worn with it to the point that a new chain will very likely "skip". My advice would be to measure the chain and replace if needed, if your new chain skips on the rear sprockets then replace them also. Then aim to change the chain as it wears out so as to avoid undue sprocket wear in future. Andrew Webster |

Replace whole chainset if replace front chainring?
Hi Russell,
Thanks loads for your reply. Actually, my chainset is all one piece (or at least it was!). It's on my 2002 Trek 4300, for which I paid £400. The bottom bracket is separate though (but the supplied BB is crap too). Thanks, Jack "Russell Seaton" wrote in message om... "Daniel Kelly \(AKA Jack\)" wrote in message ...

Replace whole chainset if replace front chainring?
you should be able to replace the broken chainring w/o any problems.
the rest of your drivetrain should continue to work fine. Andres "Daniel Kelly \(AKA Jack\)" wrote in message ... Hi, I need to replace my front chainring 'cause it's broke.
