SRAM 94 BCD narrow-wide chainrings for X01 and X1 cranks. Our NSB narrow-wide rings are CNC machined in Canada and feature a durable tooth profile that virtually eliminates chain drop. Note: The 28T – 94 BCD ring does not use the OE screws. The NSB 28T ring requires 4x M8 x 0.75 x 10mm long bolts. These are commonly available at your LBS and are the most commonly used bolt and nut combination to mount chainrings to cranks. All other sizes, 30T–36T, use the OE screws.
