Boeshield T-9: Waterproof Bicycle Chain Lubricant and Rust Protection

James W. Thompson: My bike dealer showed me this on a maintenance visit. I have used a lot of different lubricants for my recumbent trike, but this one made a marked difference which was reflected in my average speed over my route. The resistance to the pedals is almost gone. Amazing product.

Jordan Dunning: This is my preferred and trusted chain oil for my road bike! Easy to apply and works great

Ivan L.: This is my favorite chain lube. I tried 2-3 different brands but didn't like them like this one. It lasts long and keeps chain silent. I use it in mostly dry conditions and always reapply if I get my chain wet. Performs well even after couple hundred miles.
It is not the lube that you can put just before riding though. It will attract dirt and will become filthy. You need to follow the instructions to get top performing and silent chain. Apply at least two hours before wiping excess and only then ride your bike. The reason is that this lube needs to dry first and that leaves thin dry coating that protects chain. I usually apply in the evening and clean next morning. I also apply lube to each link one by one. This way it is much easier to clean, more economical and helps in avoiding drips.
And that brings me to a drawback of the new bottle. In the past nozzle was thin and long and separate from the cap. New nozzle is the top part of the cap. Applying to each chain link became harder job with the new nozzle. It is still possible but it's less precise. Also requires to clean the cap after use before closing it if you want to avoid oil on your fingers.

flashalan: Remarkably versatile lubricant. Start with a clean chain and apply one drop per link for best results. This lube replaced easy ride lube which is good too but offers no rust protection. Also left gummy jockey wheels. Boeshield t9 can be used around the shop or bike on other pivot points .. I use it on my axes and knives and more. For that reason it gets 5 * The first application was so so and only lasted 75 miles before I needed to reapply, however the second app is over 100 miles and still going smoothly. The chain does not pick up any noticeable dirt along the way. From the looks of it I can probably go 500 miles or more before a wet cleaning. I currently am relubing when it gets noisy back there . No complaints and it is waterproof too. Sometimes it feels almost to slippery.But I will take that any time.

EDIT 6/9/14
OK so after close to 400 miles of use I decided to clean my chain with my Park Tool chain cleaner. While inspecting the magnet it was loaded with metal particles. This is something I have not noticed before. Also during rides you can hear and feel the metal to metal abrasion. There was also a distinct twangy sound whenever I would put...

G. Farnsworth: I used T9 for several years with my last bike in Chicago. Lots of snow, salt, rain, and other yuckies. I used my bike as my primary means of transportation. At the end of those years (when my bike was finally stolen) my chain, crankshaft, and cassette were still gleaming silver and pristine, like when I bought them. I didn't use T9 particularly often, nor take particularly good care of the bike. I wiped it off from time to time, then added more T9 (which emulsifies the old T9), then ran a rag over it to absorb the excess. Easy as pie. The only downside with that situation was that I was using the aerosol can. When you use the can you get lube everywhere you want it, but also everywhere you don't, like on the rim and your brakes. Very annoying, no matter how careful you are.

Anyway, I bought a new bike recently and am again in a very wet place (central Pennsylvania) and using my bike every day for commuting. I asked the bike guys for advice and they suggested Purple Extreme Wet Ride. It's a heavy, waterproof oil that's supposed to last a really long time and resist water super-well. I used it for a while but it is markedly inferior in many ways:...
