    • Unior Sprocket Wear Indicator

  • Unior Sprocket Wear Indicator

    This tool can be used to check the wear of 12-21 tooth sprockets. This had typically been difficult to measure accurately. Worn cassette teeth will quickly wear out your chain and create issues in shifting or the ability for the chain to stay in gear.

    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 100N or 10kg 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. If the chain falls off the clog when applying force, the sprocket is heavily worn out and a replacement is overdue.

    Features:

    • Accurate measurement of sprockets from 12t to 21t
    • Dipped handle for comfort and grip
