Flywheel Weight Cut?

<< < (4/4)

kaw rider:
the od is where you what the weight. in this case you can take some off there.

alan:
I was afraid if I shaved off the face it could throw it self apart at hi RPM's . I do want to loose at least half the weight.

demographic:
Losing a gram off the periphery makes a bigger difference than losing a gram from nearer the centre as the centre is the neutral axis.

The outside has more inertia when spinning than the centre.

Bit like using lighter brakediscs on a roadracebike which make a bigger difference as far as lessening inertia than having lighter hubs if you get my drift.
