At Midwest we lost due to our chain falling off. Don't cantilever a swerve module off of a hard anodized aluminum/needle bearing combo.
(This doesn't mean we will never try these types of systems again. These are just examples of poor implementation.)

For what it's worth: anodizing makes the surface very hard. Anodized aluminum is much more susceptible to fatigue cracking, further shortening the life of a metal that already has a short fatigue life. IMHO anodizing, hard anodizing especially, should not be used unless wear is of concern.
