chain installation

i've been installing bike chains for a long time. its not hard to do, especially if you've got the right tools for the job.

about 5 months ago, a guy came in with a broken chain on a brand new cannondale road bike he bought from a big bay area chain (name omitted) bike store. since the bike was only a week old, i advised him to bring it back to the store he got it from, since they could at least comp him labor for installing a new chain, and probably even give him a discount on the parts, since it should still be covered under a warranty. chains shouldn't just break for no reason, especially when they are brand new.

however, he decided to just have me replace his chain, since he wanted the work done ASAP and didn't want to deal with the hassle of bringing the bike all the way to the other store, booking an appointment, and having to wait for days.

so i installed a new chain on his new cannondale, and adjusted the rear derailleur.

anyways, i didn't realize it was the same guy, but this cannondale guy ended up becoming a pretty regular customer of our shop. we built him up a track bike with a handbuilt wheelset that he's spent a lot of money upgrading lately. not unusual, people get really into that stuff.

today he came in to pick up his track bike with $550+ worth of upgrades we did to the drivetrain. as i rang him up, he mentioned the time where i replaced his chain (it was long time ago, but i did remember him). he told me that when he went back to the other shop, they looked at the chain i installed and told him that we did it wrong.

"WRONG?! what shop told you that?" i begged to differ.

he said (not maliciously) that the guys at the other shop told him that the chain pin should have been installed the other direction.

when a chain is new, it comes with one open ended outer plate, and one closed ended inner plate. sometimes the outer plate has a pin sticking out of it, which is what you use to fasten them together. the correct and easiest way to thread a new chain onto a bike, is to thread the closed ended inner plate over the cassette and through the rear derailleur. that way, the open end (with or without pin sticking out) can easily be slipped through the front derailleur and over the chainrings. then you attach the two ends together at the bottom. (if you have ever done this, you know what i'm talking about)

this is the way i've always done it. i'm pretty sure this is the way everyone does it. i didn't even question it, since its harder to do it the other way.

i told the guy that, like many other techniques related to bikes and other things, there are always differing opinions about how things should be done. some people who subscribe to a certain method assume that all the other methods are wrong.

if the guys at the other shop, in an effort to dilute their own botched chain install/derailleur adjustment, were trying to take a stab at the mechanical diligence of my shop (which is just plain bad business technique, in my opinion), i was offended. i asked him, "did the chain that i installed break, or the chain that you got from them?" and, "in the last 5 months or so, have you had any problems with the chain that i installed?"

i think he understood my point.

after he left, i even checked the shimano directions just to make sure i'd been doing it right all this time. yes i was.
