What is the minimum number of sprocket teeth when using GNK1 attachments?
When bars are installed in the holes of the GNK1 attachment for GNK1 Double Pitch Chain (an attachment with holes of both sides of the plate), the bottom of the sprocket teeth and the bars will interfere with each other if there is not the sufficient number of teeth on the sprocket. When using standard GKN1 attachments ensure sprockets with 12.5 effective teeth / 25 actual teeth or more are used. If sprockets with 30 or more teeth are required, RS standard sprockets may be used.
