New/un-used 7075 Aluminum NON Drive Side Bottom Bracket Lock Ring.  English Threaded, Shimano compatible.  These were made for the non drive side.  Not anodized and anodized clear available, message me on what you prefer.  Will send the "not" anodized version if no message received.  These screw clockwise onto the cups I have listed and the ones I have stamped with an "R". USA made.  Over 100 pcs. available.  Sold individually, one piece.  Will not work on the Italian cups listed.  English anodized cups also available in a few styles. English stainless steel drive side rings and Italian rings also available.
 "These are very useful for fixed gear bike conversions. Most track/fixed gear rear hubs come with flip-flop hubs. One side, the fixed side, has standard two-step threading for a track cog and a specific left-threaded track hub lock ring. The other side, the free side, has standard freewheel threading, 1.37 x 24, to accept a single speed freewheel. However, this free side can also be used for a track cog but it needs to be secured, which can be done with a right threaded bottom bracket lock ring because it has the same size threading. Also, if one were to re-purpose an old wheel that had an old style freewheel hub rather than a freehub, the same use of a BB lock ring would be possible."
