Late 80s Mavic made triple chainset inner rings with a high polish finish and a very useable 30 tooth size. I believe these were made for the 631 ‘Starfish’ chainsets as the previous Mavic triple cranks (630 and 635) only offered a 32 ring at the smallest. Obviously they can be used on any chainset that needs a 74 BCD ring too!
