The Good: Its a solid sprocket, never warped or bant and i bashed it constantly. ive had two now because i like them so much. light, good looking, and convenient being SD.
The Bad: NOT A MATTER OF NOT LUBRICATING. ive ridden probably 8 or 9 SD sprockets now and both of my profiles like to seize up at the adapter/spindle. it isnt coincidence and i use high end automotive silver/copper/platinum lubrication. thats literally the only downside though.
its a great sprocket, especially if you support profile. totally reliable, just be sure to use good lubricant upon application or youre fucked lol
