It's all in the momentum, a heavier flywheel has more.


i have heard similar stories before, and the debate continues. however one of the reasons for the flywheel purchase is bottom end longevity. the tour is going to my younger brother when he is ready to buy it and the aluminum wheel puts less stress on the crank and associated bearings, caps, etc. nonetheless, its already being shipped and i will let you all know what happens after i get 'er installed.
