Does hydraulic oil degrade over time? My Cycleops fluid 2, which is in good shape and I don't have any plans of replacing, seems to have a lot more resistance than it did when I first got it in the early 2000's. to ride at an easy aerobic pace now means that I have to be in the 39/21 or 23, but I seem to recall that when new the gearing was roughly the same as on the road, so easy aerobic would be in a 39/14 or 15.
Has anyone here replaced the fluid? I doubt there's any warranty claim here, considering the age of it, so may as well try it out. I'm gonna pick up a bottle of ISO46 light hydraulic oil and see if there's any improvement.
