change my chain success
Well after 3400 miles and really no stretch I decided to swap the chain out
no matter. Never actually had done that particular repair and for minute I did have to think. Lucky same type of chain Shimano 5600 just used the old one for the length of the new. I did do a double take figuring out how I was going to thread it through the derailer and after a few minutes the dawn comes and I get it all together. I must say for me this is a thrill but to some you might laugh but it was still cool. I did notice that the the shifting was more crisp for a short ride up and down the block. I put the old chain up to the new and still it really has not stretched. On the work bench it might have 1/32 of an inch stretch after 12 inches pulling on it very tight. I guess the next test will be a full ride but seems to spin well. Ok tell me I could have waited to change? What is the big thrill simple job ( but one I have never done), and is my observations about the shifting smoother something that is expected on a new chain? -- Deacon Mark Cleary |

You probably could have waited to change it, but it certainly isn't going to do any harm. If we are laughing, we are laughing with you. Are you asking what simple job to tackle next that will give you the same sese of accomplishment? You will get essentially the same improvement in shifting from washing your bike ;-) DR |

[...] , and is my observations about the shifting smoother something that is expected on a new chain? Some improvement in shifting with a new chain is expected. An old chain will have more sideways flex and hence wont tend to engage the adjacent gear as hard when pushed by the derailleur. The derailleur pivots and jockey wheels will eventually get sloppy too, and reduce the crispness of shifting you get from a new system. Cheers, James. |

Here's a handy device for chain checking http://www.jensonusa.com/store/produ...n+Checker.aspx the Park Tools CC-3, a piece of laser cut steel for under 10 bucks. BBB also make one that does the same job and that's actually the one I have. There are other brands, just look in your fave LBS. You insert the hooked end against a roller while the chain is still on your bike and the beaky end drops down behind another roller a few inches away. On a new chain the beaky end won't go down at all. The more worn your chain the further it drops down until the flat portion of the tool actually lies on top of the intervening rollers. You should have replaced the chain before then. Both Park and BBB have one side to measure a maximum of 1% elongation and the other side 0.75% elongation. 1% doesn't sound a lot but with a typical 110 links or 55 inches of chain that is over half an inch of "stretch", which is rather more than the sixteenth inch max. per foot that many experts (Sheldon for instance) recommend. On the card the BBB tool comes on. they suggest a max. 1% stretch for steel chainrings and 0.75% for alloy chainrings. Sure, you can measure elongation with chain on bike using a 12 inch steel rule but the little checker tool involves less handling of your grimy chain so you will do it more often. Chains are comparatively cheap. Cassettes and chainrings are not. Unless you have a flock of 7 and 8 speed clunkers and chase the special prices online. PH |

Chains are comparatively cheap. Cassettes and chainrings are not. Unless you have a flock of 7 and 8 speed clunkers and chase the special prices online. I don't see what's wrong with measuring a chain by a ruler. From the bicycle FAQ: "The best way to determine whether a chain is worn is by measuring its length. A new half inch pitch chain will have a pin at exactly every half inch. As the pins and sleeves wear, this spacing increases, concentrating more load on the last tooth of engagement as the chain rolls off the sprocket, thus changing the tooth profile. When chain pitch grows over one half percent, it is time for a new chain. At one percent, sprocket wear progresses rapidly because this length change occurs only between pin and sleeve so that it is concentrated on every second pitch; the pitch of the inner link containing the rollers remaining constant. By holding a ruler along the chain on the bicycle, align an inch mark with a pin and see how far off the mark the pin is at twelve inches. An eighth of an inch (0.125) is one percent, twice the sixteenth limit that is a prudent time for a new chain." http://www.sheldonbrown.com/brandt/chain-care.html The other thing are the cost of chains. Unlike the 5/6/7/8 speed chains that I agree are "comparatively cheap," the cost of 9, 10 and now 11 speed chains are off the scale! 9 speed are still kind of reasonable and can be found around $20-35. But, 10 and 11 chains can cost anywhere from $25 on up!!! Some like Wipperman run in the $60-80 range. Outrageous. Good Luck! |

You can go further with a single speed, can't remember how far, but it is given in Wipperman's catalogue/ instructions avaqilable on internet and is much more than cycle industry 'thinks'. |
