They can also be used with non-Wolf Tooth branded single chainrings as well that feature a 110mm or 130mm BCD. Coming equipped with a tough aluminium construction, this kit is a great upgrade for replacing old or lost chainring bolts and breathing new life back into your setup.Wolf Tooth designed these bolts to be the best on the market. These single chainring optimised bolts have a 4mm hex socket on the bolt and a 6mm hex socket on the nut, so no spanner is needed.
