Neptune Helm Sprocket (Red) (44T)
I really wanted to like it. Looks great and the red has a nice color to it but that's about it. Rough machining with visible tooling marks that should have been removed before anodizing. I had some initial fitment issues and holes are off centered. Once installed it appeared out of round and not worth what I payed. The stock SE part will go back on and this will go in the junk parts box.
