Supplies needed: A wire brush, lube, rags. That's it! As you might guess, I have the afore mentioned supplies all wrapped up in a handy dandy kit for sale for your drive train cleaning pleasure. Email me for details. 2 bottles of lube?? Yep, 2 bottles. The Dumonde Tech (the green stuff) is really, really, really good on chains. The TriFlow (black bottle) is a slightly better penetrating lube for derailleur pivots as well as a kitchen sink full of other uses both on and off the bike. Additionally, TriFlow comes with a handy dandy extension tube that fits into the end of the bottle making the job of getting lube into all those "hard to reach" spots an easy task.
Next, move to the outside of the chain. To make this easy, shift the chain onto the big chain ring. Again, back pedal while holding some pressure on the wire brush.
To finish the chain, brush off the side plates. Don't forget the back side!
Next, clean the rear derailleur pulleys with the wire brush. Again, you're back pedaling the bike to do this. Go easy with the pressure of the brush so you don't bind up the drive train which will cause the chain to fall off.
Go back to the chain rings and give em' a scrub. It won't take long to get the grime off the rings.
As you get more comfortable working with the brush, you'll learn little tricks on where to hold the brush and angling the brush to really get into all the nooks and crannies. At some point, you'll have to shift the chain into a different chain ring to allow you to get all three chain rings. (or however many you happen have).
Next, go to the cassette and get to work. If your bike is in a bike stand, pedal forward slowly and move the brush to different areas of the cassette. Be careful not to get your brush/hand/fingers tangle with the spokes of the wheel as it's spinning. If you're working on the bike on the ground and can't pedal forward, patiently use the brush back and forth to clean things up. Again, you'll have to shift the chain a few cogs to clean the entire cassette. At this point, you're done with the wire brush.
Get in your kit and grab a rag. Use the rag like dental floss to get in between the cassette cogs and make em' look new. The first few times you do this, it will feel (and be) a bit cumbersome. In time, you'll be a cog flossing pro and "wowing" you fellow riding partners with how clean you bikes' drive train always seems to be.
Move down to the rear derailleur and clean up the jockey pulleys. Use light pressure with your fingers and back pedal to clean the pulleys.
The rear derailleur has 10... count em'.... 10 pivots on it! Get in there and clean them up as best you can. You won't get them perfect, but that's OK. Just try and get the majority of "gunk" off. While you're at it, clean up the pivots on the front derailleur as well.
Take the TriFlow and lube all of the pivots on the rear derailleur. You only need a drop or two on each pivot.
Same thing for the front.
Next, take the Dumonde Tech and lube the chain. I like to lube on the inside of the chain because that's where the chain is coming into contact with the chain rings and cassette. Use the lube sparingly. You really only need a little bit on each roller of the chain. How much is a little bit......
..... it's about like this. You're trying to avoid getting lube all over the side plates of the chain. An over lubed chain will just attract dirt and grime making your next clean-up more tedious than it needs to be.
So, at this point, you've got lube on the chain, and all of the derailleur pivots. Slowly shift through all of the gears. This helps to work the lube into the chain and derailleur pivots. The more you do this the better. It's best to let the lubes "marinade" a little while. A few minutes is adequate. To finish, wipe off the excess lube from the chain and derailleur pivots and GO RIDE!!!!
