Boeshield T-9 Bicycle Lubricant - 4 oz. Reviews:


I've been workin' on the Chain Gang....

Arizona is filled with fine dust. It ruins chains that are "wet" lubed. Years ago I switched from wet (oil based) lubes to "dry" lubes to prevent infiltration of dust that was wearing out my chains in 1500+/- miles. (Also very dirty and made for everyday epic cleanup periods). I've used other teflon and/or parafin based lubes that did the job but required very frequent reapplication as the lube would migrate and/or disappear. T-9 on the other hand clings and stays in place for a much longer time! I get 4-600 miles before reappling lightly. The chains on my four bikes now last 3-4500 miles before replacement. Completely remove any trace of old (or original) lube before applying T-9 the first time. This will guarantee adherance to the metal. Allow overnight to dry! Just wipe the chain with a wet "baby wipe" every couple of rides. Perfect product, perfect results.

Best I've tried

I've been working on bikes since 1976. This is the best stuff I've found and I've tried most of the others.
Here's how I use it:
Using a Park chain scrubber, I insert the T9 from the top holes of the chain scrubber and pedal backwards.
I cover the holes with a small square of paper towel first to slow the application of the T9.
Then I remove the chain scrubber and run through all the gears. This coats the cogs, chain rings and derailleur plates.
I tune up all my friend's bikes each spring. The very first thing I do is I check the chain with a chain checker. Chain wear is almost unobservable.

T-9 excellent quality and value.

This lube has so far outperformed the others I've tried in terms of its effectiveness at lubrication on my chain, (I haven't used it elsewhere yet, but plan on doing extensive winter lubrication prep. with it on my winter bikes), keeping it cleaner longer. Once you apply, and I did so sparingly, one drop per chain link, and let it dry for at least two hours per directions on bottle, there wasn't even any excess to wipe off (and attract dirt and build grime). Chain has remained clean for two weeks now, riding every day at least ten miles, as we've had very nice late-October weather. Will update when wet weather arrives over next week.

Excellent all-purpose solvent and lube

Put this on my dirty chain and it ate everything else away, almost like a degreaser would. Then it ran smooth and buttery. Also put it on my brake and shifter cables, then disassembled my shifters and put a drop of this lube on every component in there. They shift better than ever now. Lasts a long time. I like that it dries to a thin waterproof wax finish.

Impressed by the quality of this lube, I used it on a few non-bike related items as well. I oiled my pocket knives with it and applied some down inside a padlock to keep it working smoothly. Absolutely no complaints on either count!

Best lube to date!!

I have tried many lubes in my years of cycling; you can see my review of other lubes on this website, and this is by far the best lube I have ever used. It almost magically picks up no dirt and keeps the drive train VERY clean. It lasts for many, many miles before needing to be reapplied and doesn't wash off easily. When it is due for reapplication simply wipe the chain down, apply, let dry for 2 or more hours and then wipe off excess! Excellent lube!! Highly recommended!

Good Product; wish bottle was same

The lube works great on my mountain bike chain. I'm one of the fanatics that places a drop on each link of the chain and catches the excess in a bottle. The former packaging bottle had a twist off cap so I could pour the excess back in. The new bottle has a nipple which cannot be removed easily and it would be ruined after a few removals. So I saved the old bottle and will put the lube from the new bottle in it

Love it

After 10 years of experimentation, this has become my primary commuter lube. It doesn't attract dirt (like wet lubes) and keeps the drivetrain quiet.

I like it very much in Texas for dry conditions, but I'd probably go back to a wet lube in a rainier area.

I'd only like it more if it was all natural like the Pedros Bio lubes.

had tried every available lube out there. For me,this one does the BEST all around job. Instead of having to constantly switch from a WET lube to a DRY lube depending on the conditions. I typically get 250=3000 miles between lubes. I figure if BOEING created it for there gear,it's gotta be good enough for my bikes. I was right. HIGHLY RECOMMENDED!

Great Lube

I simply apply to the chain, let stand over night and wipe off the excess. It lasts for hundreds of miles. Amazingly does not pick up dirt. I also apply to my cables and shifters, great lubricant.

Best lubricant I've used. Lasts 100-200 miles typically. I tried another lube thinking it might last longer on my commuter bike but switched back to T9 since it did a better job.
