A few weeks ago I was riding and I had to shuttle my bike up some stairs. I typically leave my valve open on my water bottle when I ride...well...the Cytomax I had in there dripped out all over my front brake. It was the loudest thing I have ever heard for at least 5 miles. The braking was v. poor as well. My guess is the sugar heated up and formed a hard crust on them. Just thought it was funny...we all worry about oils etc....Cytomax...be warned!
