This was the first time I ordered this type of chain lube and I immediately became a fan. This lube is much thinner than the other chain lube I used previously (White Lightning Clean Ride) and seems to be much more effective in improving shifting and reducing chain noise. This has become my go-to and I will be buying again soon.
I've tried a few different lubricants for my chains over the years, all of which worked fairly well. However, I have found T-9 to be the best one for my use, which consists of road riding for fun and for commuting. I don't encounter all that much dirt and gravel along my routes, but I still find that my chains can accumulate a lot of gunk quickly. What makes T-9 more effective is that it doesn't seem to attract dirt nearly as much and my chains stay running smoothly. As my headline suggests, I'm familiar with some of Boeing's other product offerings, and I always find them to be carefully engineered and the best of their kind. Enthusiastically recommended.
