Sprocket Wear Indicator

  • Material: special tool steel, hardened and tempered
  • Surface finish: chrome plated according to ISO 1456:2009
  • For HG and IG sprockets

How to use the tool:
The sprocket wear indicator is used to determine the condition rear sprockets. It can be used to check 12 to 21 tooth sprockets.

Procedure: The chain is put on the sprocket and the tool placed with its round end between two teeth on the upper sprocket side. The last chain link is moved away from the sprocket and a force of 100 N or 10 kg is applied to the tool in the direction of sprocket rotation. Now the last chain link is moved towards the sprocket. If it skips easily to the cog the sprocket is in a good condition and will function flawlessly even with a new chain. However, if the last chain link gets stuck on the tip of the neighbouring tooth or if we have to force it to skip on the cog, the sprocket is worn out and should be replaced. In case the chain falls off the clog when applying force, the sprocket is heavily worn out and a replacement is overdue.

Perfect for my dog that destroys everything
Color: Purple
It’s important for you to know: it’s hard. It’s a hard toy. It’s a bit heavier than normal dog toysx but it’s perfect for dogs who destroy every toy.. I have a 30lb 2 y old baby and they keep her entertained for sure. They are s good size. I honestly love it. My dogs love it too. It was a good purchase :)

Indestructible dog toys
Color: Blue
These are indestructible toys. They do, however, hurt if the dog comes and drops it on your head while you’re sleeping. It is also quite scary when the dog drops it on the tile in the middle of the night. Be warned ;)
