I'm sure jackedup00 could use an extra one. Bet the kid has a 38 lb right foot.

Well i did some more research and there is definetly a cast and forged variant of the 8 bolt crank.

There is some conflicting information out there:

Im still convinced it's cast. Im looking for some concrete evidence before i commit to this crank.

Ding it with a hammer. Thud means its cast. If it dings = forged.

WF is their forging plant.
