SRAM X-SYNC 94BCD chainrings are the correct replacement for XX1 and X01 cranksets running the 94BCD 4-bolt pattern. Wide-narrow tooth profiling keeps the chain seated without a chain guide, and the hard-anodised aluminium holds up to the demands of technical singletrack riding.

Highlights

• 94BCD 4-bolt mount — fits SRAM XX1 and X01 cranksets
• X-SYNC wide-narrow tooth profile eliminates chain drop without a guide
• Hard-anodised aluminium — tough, lightweight, and wear-resistant
• Designed for SRAM 11-speed MTB drivetrains (XX1, X01)
• Available in multiple tooth counts

Wide-narrow on technical terrain

X-SYNC wide-narrow teeth lock into the alternating gaps of the chain's inner and outer links, holding the chain on through drops, rough landings, and pedalling under tension. The result is a clean 1x setup that performs reliably without the weight and complexity of a front derailleur or chain guide.

Fit and compatibility

The 94BCD 4-bolt pattern is specific to SRAM XX1 and X01 cranksets. Confirm your crankset model and tooth count before ordering. Designed for SRAM 11-speed chains — not compatible with 12-speed Eagle chains.
