I replace my chain every year, more or less. It tends toward less as I don’t have a set anniversary for new chains. Usually I notice the shifting is lagging a second and it dawns on me that the chain is in need of replacement. In my youth I would keep the same chain on the bike forever. I even used to take it off, and reinstall it inside out (?!) thinking…thinking that I was a cheap idiot. The result of that was the rear cogs were always ruined too, reinforcing the cheap idiot thing. Since replacing the chain on a yearly basis I’ve never had to replace a cassette. I’ve heard that the Fabian Cancellara’s of the pro peloton get a new chain once a week. The pros are fifty-two times more mighty.
This most recent chain replacement had me using a Campagnolo Chorus chain I had attempted to install on another bike and failed. I shamefully put the chain on a shelf until I had stocked up on Campagnolo’s special bullet shaped, don’t drop this on the shop floor or you will never find it, you only get one shot at this, very special chain pin. Maybe it’s like redoing your handlebar tape or filing taxes; these jobs only done once a year never go perfectly. Installing the Campagnolo chain is like what I imagine arming a field tactical nuclear weapon is like. It is cramped. It requires small hands. It requires excellent vision. It requires mechanical skills and you only get one shot at it. Luckily, for me, the whole mess was contained with a KMC 11-speed quick link, whew, done and dusted.
My point is, when one changes just one component on one’s bike, the change is very noticeable, The first few pedal strokes out on the road with a new chain is a subtle revelation. It feels different. It feels better. Damn it feels excellent.
Or is it all in the mind. This article was linked in the Velominati posts a while back. In a world full of anecdotal evidence I do enjoy an article where our perceptions are put to the test. Maybe my new chain feeling is all in my head? Who cares, I can still enjoy it and “in my head” is where enjoyment happens anyway.

Yup, missed it by 1/8th bean of a lord's left testicle (or some other particularly obscure representative base).
@KogaLover
One tool to check them all. You are correct, it is only the width of the chain that decreases as you add cogs to the cassette. The length from pin to pin is constant... unless you apply too much V (or not enough care), in which you have to swap out the chain.
Also, a 6 speed steel steed!?! Pics pls.
@DeKerr
Yup. Link length hasn't changed. Park tools does make another chain checker that costs about 3 times as much to tell you the same thing the one I posted does. For a home mechanic this will work perfectly.
An accurate steel ruler works fine to check chain wear too: any more than 1/16" 'stretch' at 12" and you should replace it.
Ironic that chain is still specced in inches. If only Shimano's 10 Pitch system had taken off...
@DeKerr
Yeah, but then @TBONE ruins the mystique by admitting that he avoids Rule #9 conditions. Not that I ride in the rain much, mainly because it never fucking rains in the desert. A quick look at the weather history shows it's only rained 1.75cm so far this year.
@frank - I agree with the DuMonde Tech comment, love this stuff. Thanks for bringing it to my attention with your Reverence article.
@wilburrox
Tyres, now thats a whole other thread!
@bea
Quite possible now I've read the wiki list of uses for this natural wonder substance. Keeping sheep dry to nipple lube and everything in between! Now where's the VMH put her hand cream?
@Ron
Good stuff that fizik. I must admit that I am changing bar tape at the half-life just for the sake of switching from black to white, or Cinelli to 3T to ZIPP, etc. And note that I changed the Campa hoods with the matching bar tape as well. I did ride fizik years ago but witnessed the micro-whatever surface degrading too quickly. I think ??
Correction: It was ZIPP CX tape that lost its thin surface faster than you would imagine.
@Teocalli
Um...yeah. Woopsiedaysies.
