Not a 292 crank but a 250,
IIRC, Mike Kirby had told me he had lightened a couple 250 cranks by about 18 lbs & it did not help his ET or MPH one bit.

Those cranks he lightened just made his wallet lighter with no benifits.

So he just uses standard 250 cranks that last just as long as his lightened one do if not longer.
