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.

disappointing... buyer beware
Size: XX-Large, Color: Lavender White Windowpane
careful there is no pocket? what kind of essential long sleeve shirt arrives without a pocket? I took to the cleaners to have pressed, and just got it back today. so I missed the return window. I am disappointed, and a bit frustrated, it's never been worn and will not be without a pocket....

Great value
Size: XX-Large, Color: Navy White Diamond Geo
Nice shirt for the price. Needed a budget shirt to wear with a suit and this fit the bill. Fits well. Is a little thin, you can see through it if not wearing an undershirt.
