Really? Then perhaps you can explain how a muscle group hundreds of times weaker then those in your legs can easily accelerate a "heavy" wheel to typical MTB speeds in an instant while the much larger/stronger group apparently has great difficulty.

Please ... explain this my friend. Apparently the weight weenies are surrounded by a special aura that allows them to take everything completely out of context while maintaining a straight face.

Granted, this is not an empirical argument. But I've never heard one in which people did not take the system out of context by ignoring the entire mass of the system including the rider and non-rotating bicycle parts.
