What can I say about Squirt? Plenty. I’ve been using it now for two seasons and it has been a god send in the lubrication of my drive-train! I did a 250 mile backcountry MTB hut trip trough western Colorado last summer and was in charge of supporting several bikes during the trip. I used Squirt exclusively one all the bikes and we had no troubles at all! We saw the full range of conditions during the 7 day trip. From pouring rain and mud to severe dry and sandy conditions, Squirt handled it all without complaint!
