Hi all - I am eyeing up an HG 68 and have read that the under carriage is one of the most important things to look out for. Does anyone have pictures of what good/bad sprockets look like?
Thanks,
Jeff
A new sprocket will have about a 3/4" flat across the top of the tooth. Most are replaced or repaired when the flat is 1/4" or less.
Good Sprocket
