Excellent for anything that needs to be lubed.
Nothing at all.Overall Review: This stuff has been around since my dad's dad started biking. Alright, I'm not sure about that but it's been around for a hell of a long time. Since it's still here, that's evidence that it's some pretty good stuff. In the world of Lubes, survival of the fittest is king. If it does it works great, it lives. If it sucks, they sell it to Finishline and sell it for a $1. Boeshields' T9 is King. I'm pretty sure they haven't changed the graphics of the container since it was first in production either. I use this on my chain, derailleurs, shifters, cables, seized bolts, and friend's disc brakes rotors. If you need something to slide freely, this is the stuff to have. I would recommend this product to ANYONE.
