The SRAM X-SYNC Direct Mount Chainring is built for riders who want to run a single-ring drivetrain without a chain guide — because the ring itself does the retention work. It mounts directly to crankarms with a splined direct-mount interface secured by three bolts, eliminating the spider entirely for a cleaner, lighter setup. The X-SYNC tooth profile is what makes guide-free riding viable. Teeth are taller than those on a standard shiftable ring, with a squared-off top rather than a triangular tip. They alternate in a wide-narrow pattern that aligns with the inner and outer link plates of the chain, holding it in place under the kind of rough, chaotic input that would throw a conventional ring. Mud-clearing recesses at the tooth base keep engagement consistent when things get dirty. Available in 34t and 36t, both in a 6mm inboard offset for standard chainlines — if your bike runs a Boost rear hub standard, confirm your chainline requirements before ordering.
