I purchased an SiSL crankset to go in my BB30 frame. I'm confused about the spider lockrings as there appears to be two different types of KP021 lockrings: a silver one that is unmarked, and a black one that is marked Pressfit30. I have the later. Will this cause any issues with installation or chainline on my BB30 frame? Looks like the rings may be the same thickness, with just a slight difference in the taper to allow for extra clearance? Thanks for the help.

There will be no problems if using black one.

+1.. No problems

Awesome, thanks guys.

No problem like already said. Just problems to use the silver one on a Pressfit 30 bike. To tight, that's why the ends are a little shaved.
