Sugino Royal bottom bracket lockring (or locking ring if you prefer), hailing from Japan and in production from the 1970s to the 1980s (yet still new & unused after all this time). Made from steel and weighing in at 12 grams. A fine choice for keeping your vintage bike authentic, but also great for any other compatible bike.
If you're taking part in L'Eroica or any other vintage event, this is fully compliant - so rest assured, the pre-1987 police won't lock you up for having the wrong lockring
OVERVIEW
TECHNICAL INFO
Bottom Bracket Thread Type - this must match the thread of your bottom bracket for the lockring to fit.
Thread Direction - most bottom brackets only have an adjustable cup on the non-driveside of the bike, so lockrings mostly thread to the right (clockwise), regardless of the thread type. However, some bottom brackets have adjustable cups on both sides so the thread direction may be different.
Thickness - this is rounded to the nearest 0.5 mm.
