Where should one break a chain for fixed gear. My LBS advised me not to use
the proprietary quick link as it's breaking strength was less than regular links. However, with new chains, I worry about the integrity of rejoined links (ie. short pins with mushroomed heads). As an aside, can anyone recommend a good economy chain for fixies? Cam |

A standard SRAM PC48 is fine if you're using 3/16" sprockets and chainrings. |

I've used SRAM/SuperLink QR links on both my tourer and my ATB for
decades with no breakage problem, but fixie chains may be a special case. Break the chain anywhere with a chain tool. A chain is and endless, uniform circle, there is no correct or incorrect link to "break" on it. - - "May you have the wind at your back. And a really low gear for the hills!"

It looks good and that alone inspires more confidence than the black $6 generic BMX chain. According to the package it is intended for "citybikes, BMX, track and indoor sport" and "breaking load: 8.200 Newton". Since I weigh 200lbs and stand on the pedals, this last one has me a little worried, but I'm hoping it's a dot thousands rather than a decimal point. I joined it with the supplied old style 3 piece spring clip master link. I have about four hundred kilometers on it in mostly clean dry conditions and have not broken it YET. Marcus |

If the lbs is selling weak quick links, they should find better ones. I have never had a strength-related connector link failure with a single-speed chain in 40 years of riding bikes. (I've had a couple of the old-style ones become unclipped because of stuff hitting them and knocking the spring clip off, but that's a different matter, and less of a concern with the SRAM-style links.) Remember, regardless of the fact that it's being used on a fixie, the load is always in the same direction as far as the link is concerned, and unless the chainline is running at an angle, the load is much more even than on a derailleur-equipped bike. I would expect no more trouble with the chain on a fixie than on any other bike, despite the fact that it's in motion continuously when the bike is moving. If you don't learn to modulate your leg action to avoid wasting power while riding, you'll wear *yourself* out before you wear out the chain. >However, with new chains, I worry about the integrity of rejoined >links (ie. short pins with mushroomed heads). A valid but in my opinion often overstated concern in this instance, and part of the reason why the SRAM connectors are favored so widely. On a single-speed setup, the side forces should not be present which would tend to hasten failure due to pin looseness, so it's probably less of a concern than on multispeeds. Since I've always used connector links on replacement single-speeds of mine, I've never had to worry about it. >As an aside, can anyone recommend a good economy chain for fixies?

Even if it is, these are certainly strong enough. Remember that some fat ol' guy struggling up a hill in his mountain bike, in his granny, exerts more stress on the chain than Marty Nothstein in a sprint. (Hint: It's because of the granny.) Lots of folks use these super-links with no trouble, No reason to believe you won't. > However, with new chains, I worry about the integrity of rejoined > links (ie. short pins with mushroomed heads). Much more of a concern than the super-link is. I use Sram. Since I*have a bunch of 1/8" sprockets, I use the 1/8" chain, the SR-1. $10-$15. If you have 3/32" sprockets and chainrings, use the 8-speed chain, it's cheaper. -- David L.

I think you mean 3/32". That's standard derailleur chain. Track chainwheels and cogs take either 1/8" or 3/32". Phil Brown |

I think the change to the use of the comma to define thousands did not happen during translation to english for the packaging text. Marcus |

That is it!!.....................The answer for the ?? Whether you use "road pitch" or "track pitch" 1/8" (track) chains are strong, cheap and work great. They do make a little noise if you are running road pitch gears |

The torque about your rear axle is related to gear ratio, but your chain couldn't care less what the rear sprocket is (when considering tension anyway). The tension in the top run of chain is determined only by the ratio of your crank length to chainring diameter and the force applied to the pedal perpendicular to the crank. |
