Where to get individual sprocket?

Useraid

Was cleaning cassette and one of the sprockets went down a drain. I can't seem to see where to buy them though?

It is:

Y1Z81200N Sprocket Wheel 12T (Built in spacer type)

Try petra cycles.

Depending on the cost of the single cog, you could always just buy a new cassette.

Sooner or later, your cassette will be worn and need replacing. When that happens, it won't be the 12t which is worn, it'll be the cogs in the middle, the 15/16/17t because you probably spend most of your time in those and just use the 12t on downhills so it won't be worn at all. So you can just swap-over to the new cassette and carry-on with the same 12t.

Alternatively, some nice person on here might have a worn-out cassette that they've just kept in their spares box and will let you have the 12t off.

Thanks for the help. I emailed petra but did not receive response yet. I did however get the drian open and have now recovered the sprocket.,thankfully as I would rather replace the cassette when it is more worn, probably just done 1500 miles at the moment.
