Article – New Chain Part 1

IMG_0526

So there I am with a big grin on my face because I’m doing one the things I love, working on my bike. I had just install a new E*13 42 tooth cog, cleaned the freehub and the rear derailleur. I have decided ahead of time with this job it might be reasonable idea to install a new chain.

I had no idea how many miles was on the last one and recently shifting was less then perfect. Additionally I was upgrading from the SRAM 1031 to SRAM 1071. The biggest difference is the HollowPin saving some weight but not super light.

With the new gear setup of 32 tooth sprocket and 11-42 tooth cassette I only needed to remove a few links. Upon the removal process I notice the compound on the chain was significant. Through little research it appears to be a multitude of things. As it felt like grease the details I found called it factory oil lube. The manufacture uses a heated oil to penetrate all aspects of the chain for a few reason. Packaging, since there is no telling how long this chain will sit on the shelf waiting to start it’s life on someone’s bike the compound help moisture build up that could cause corrosion. Lube, basically primed and ready to go no additional oils or wax needed.

Dirt magnet, I wiped off as much as I could by hand. Seriously, this was like having fly paper on my bike for dirt, dust, pine needles and crunched up leaves. Logic at this point was telling me to clean this thing with degreaser or something to strip every bit of this stuff off. My drivetrain was running better and shifting well, so the combo of everything was working somehow underneath hazy powdery coating of grime. Research on cleaning/strip the chain suggested an automotive degreaser or gas. I also, found an article from Sheldon Brown. he makes some points to why it should be left on but if you feel the need to remove the factory lube he is offering a service to help.

At this point I have tried the application of wiping off the extra lube and ridding. Seriously this chain picks up everything! Keep an eye for Part 2, where I will have degreased/stripped this chain and retested whether or not it continues to be a dirt magnet.
