Shimano Crane jockey wheels (or derailleur pulleys if you prefer), hailing from Japan and in production during the 1970s (yet still new & unused after all this time). Made from steel and weighing in at 39 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 a similar vintage event, this is fully compliant - so rest assured, the pre-1987 police won't lock you up for having the jockey wheels!

▼HELP SECTION

Teeth - the tooth count has increased with the introduction of more gears, but this happened very gradually so 10 tooth jockey wheels were standard for a very long time.
*Compatible Speed - the number of cogs the jockey wheels were designed to be used with. When using derailleurs for indexed shifting it's important to stick to this, but friction shifting is much more forgiving so you're unlikely to have any problems using the next speed up or down, providing all the measurements are correct.
Diameter (OD) - the diameter of the jockey wheels, from the outside edge of the teeth. It’s important to stay close to the ones you're replacing to ensure they fit.
Thickness - measured at the widest point, by the centre hole. The spacing has generally become narrower over the years to accommodate more gears.
Centre Hole (ID) - the inside diameter (usually inside the bushing/spacer if present). This rarely presents a problem, but some older jockey wheels have a different diameter so it's worth double checking.
