Ok, a friend brought this up, at first I dismissed it butthe more I think about it the more it's starting to bug me. I commute, but I need to have access to my car at work. On Monday's I drive in and ride home, leaving the van at work, ride back till Friday when I drive home etc., Through the week, I store my bike in the back of my van. A friend pointed out that the internal temps in a car can reach up to 180 degrees in the summer time. When I repack my bb, wheels, etc., I use pretty cheap grease. Is there any chance that grease is being damaged in the heat, ie, getting runny or not protecting like it should? Thoughts?
