The G3 also came out with an alloy bowl, the difference is in the governing system.

The G3 has a plastic arm around the post, that the cable hooks into, the G2 has a metal lever system away from the post.

The G3 has a plastic "Flag" while the G2 has a large metal one.

In this photo, the one on the left is a G2, the one on the right a G3.
