Great for my mtn bike!
Like Dominick stated, this is great stuff. I like the smaller bottle to use for application of the Extreme Lube. When I got the large bottle, I had to shake it up for a minute to mix it together which was a little different for me. I too am a Park City based mtn biker, lots of dusty trails on the cross-country trails I seek so this stuff is ideal. Nothing like having well lubed equipment for excellent performance.
