We have this lube in the shop here at Bike Tires Direct. I never really thought about it but have always used it. The thing that I like about the boeshield is the ease of use. You just pour it on your chain, let it sit for 2hrs, wipe it clean, and your done.
Oh yeah It works great too. Plus it was developed by The Boeing Company for planes-what more can I say?
My LBS recommended this lubricant for my chain and I'm glad he did. I've tried another brand of lubricant, but found that I had to clean the chain way too often as it got dirty pretty quickly. This product keeps the chain clean and squeaky free. Other rides ask how I keep my chain and cassette always looking new, they think I sneakingly polish those parts while they aren't looking. I am anal about keeping the chain and cassette (or as I sometimes refer to as sprockets) clean as I don't like them dirty and I don't like having to replace parts unnecessarily . It's easy to apply, After cleaning the chain with the Parks chain cleaner tool, I spin the chain backward slowly while adding a drop to each link, let it set a few hours and wipe the chain to remove any excess. The lubricant lasts a long time since you aren't cleaning and lubing all the time.
I only use this lube on my chain, use the other lubes i tried on all the other drive train parts. I like the way it applies, stays on and cleans up, most of all a quiet chain. Ia'm a fanatic about a clean, quiet chain, wipe chain, put this on each link, wipe next day, wipe down after every ride.
Loud, does not last long (e.g. I have to reapply every 100 miles) and even when fully saturated, it does not work as well as Chain-L, Prolink Gold or Clean Ride.
Stay away. What's good for airplanes (Boeing) is not good for a chain.
Boeshield T9 is good for a lot of stuff, including protecting metal. However, as a bike chain lubricant it is not so great.
Friction Facts rates T9 as a lubricant something like 40 out of 53 lubricants that it tested in the bottom third for sure. There are many lubricants that are considerably better than Boeshield. I used Boeshield and gave it a try and compared to the other lubes that I use I found that Friction Facts results seem to be right on. It didn't last as long or provide as quiet and smooth of a drive train as the other lubes I use (and that I wish Bike Tires Direct carried - like the Rock 'n Roll lube series that were in the top 5 of the Friction Facts test).
I've been using this chain lube on my $3000 rode bikes for years. It's the only one I buy. I read about it in Bicycling Magazine years ago, tried it, liked it and haven't used anything else. Price is a little on the high side but it's worth it.
I wipe down my chain and lube with T9 every 100 miles. This keeps the chain quiet and the last chain didn't register any wear after 5000 miles (using the Park CC-2 chain wear tool). After letting the oiled chain set for an hour it gets wiped to remove the excess oil & grime leaving a nice shiny, clean and quiet chain.
Used to amateur race and the team would always tell the wrenches If its not Boeing, I'm not going.
Switched to Dumonde Tech for a year a few years ago at the insistence of another rider that it was so great-and it was a big mistake, gunked up my dura-ace drive chain requring a heavy duty tank soaking to get it back to normal.
Remember If it's not Boeing, you are not going.
Boeshield is not recommended for cyclists that spin faster than a turbine engine.
I've been using Boeshield T9 for years! It doesn't seem to attract dirt and keeps the chain running smoothly. (It was originally developed as a lube by Boeing. Guess if it's good enough for them...)
I commute to work. Sun, rain even a bit of snow. There's always grit, gravel and road debris being kicked up into my chain, gears and hubs. This lubricant works great. I've tried others, but nothing compares to its lasting power and ease of application. I've trusted T9 for seven years, 16,000 miles and wouldn't use any other.
I've been using this chain lube on my bike now for over a year. I like its consistency. It does attract quite a bit of dirt which means for more cleaning overall, but that's something that should be done anyway. When I've just lubed everything...it's like butter. Also, despite the increase in re-lubing, I still haven't used my first bottle...over a year later.
