I happened to run across a new Swedish study:
PLOS ONE: Endurance Exercise Enhances the Effect of Strength Training on Muscle Fiber Size and Protein Expression of Akt and mTOR

which found it's good to ride before lifting. Some of you here may know that I've been in favor of doing this for years. Riding first didn't hurt their increases in the weight room, plus they got much better muscle fiber development than those who did not ride first. Which is also what I've personally found.
