I hadn't really thought about it until the other night when I was riding home, but I have noticed that my bike seems to be riding considerably stiffer now than it does in the summer. I am sure that this because the colder suspension oil is cold and therefore raises the damping level. My question is how much does the oil warm up when you ride? I guess I don't know how much cycling the oil actually does through the dampers. Is it enough that on longer rides it will warm up and thin the oil back out? I am thinking about backing the rebound damping off a little, it just seems like the suspension is not quite quick enough.
