Review on 🚲 RocRide Narrow Wide Chainring 104 BCD for Optimal 9/10/11 Speed Performance with Secure 4 Bolt Mounting by Paul Abs

Inner diameter will not fit multiple cranks even if they are 104 BDC. The four holes match, but don't slide into the crosses because they are underprocessed. Diameter matching the flange ends. These chainrings are only suitable for very cheap models under 50€. Cranks or just the outside of the cross on the best cranks not designed for a chainring to fit outside. I threw two in the trash, 32 teeth and 30 teeth. Waste of money, not recommended. If you want similarly cheaper sprockets that will fit, buy Snail sprockets.
