Maintenance Your Hollowtech Style Cranks/Bottom Bracket Cups Regularly
#1
Just wanted to drop some positive encouragement for taking your spindle crank out and getting some fresh grease in the cups and on the axle regularly. This will dramatically improve the performance of your drivetrain. For example on how often, I had fully overhauled my bike back in March, when I converted it back to urban street from the snow conversion. It's only May, not even 300 miles on it since then, and I took it apart yesterday, cleaned it up and slapped some fresh grease down. There was some awkward friction and noises coming from down below, but today it rode smooth as butter.

Also, remember that the rear hub is much like the rear tire (given drive force), and needs fresh grease at least three times to the one time that the front needs. I fully overhauled mine while I was at it and thanked myself immediately when I hit the streets today.
