SHortly before OnDunes closed its doors I had purchased a 520 rear aluminum sprocket. I remember at the time quite a few people were waiting on these to be shipped. I've been impressed to say the least with how little wear this thing is showing and would like to pick up a couple more in different sizes assuming the manufacturer can still produce them. I recall the manufactuer being a three letter ancronym. Something like PPI.... Does anybody know the scoop on who produced these aluminum sprockets and how I can contact them?

 

They sold two, RW and PBI
