FBinNY: thanks! I will try this later today.
BCRider: very interesting, this is the first time I've heard of cross chaining. After a google search I see similar info to what you say. I've actually been riding with the two biggest gears about 80% of the time...I just like to max out the resistance and speed I guess, I had no idea this is harmful. What do experienced riders do when they want max resistance?
