North Shore Billet 1x 64/104 BCD Variable Tooth Chainrings

104 BCD Chainring by North Shore Billet

The NSB 1x 64/104 BCD narrow-wide chainrings use a proven variable tooth pattern mated with a standard chainring tooth profile to help retain the chain on the front ring during all types of riding. The profile maintains excellent wear for a durable product and has an optimized chainline for 1x systems. Utilizing the most common bolt pattern – 104mm BCD – these rings can mount to almost any crank.
