Variochain upper chain tensioner pulls the chain downwards instead of pushing it upwards.
This makes it possible to use one chain with a greater combination of sprockets.
Therefore the necessity of using worn out chains with some sprocket combinations is a thing of the past.
For this tensioner we use a rugged, wear resistant and friction reduced synthetic material, which is securely bolted onto a CNC machined mounting plate.
