I picked these 15T Sprockets for a couple of CRF50 projects I and working on. They don't look like the photos in the ad where I purchased them.

Anyone have any experience with them? I am asking as I saw some older posts in a couple of forums where people had issues with either the Sprockets stripping or cause damage to their spindles.

Would like to know weather they are okay to use or I should return them for some Sunstar Sprockets.

Thanks guys.
