SRAM X-SYNC Direct Mount Chainring for BOOST
SRAM X-SYNC Direct Mount Chainring for BOOST Info
The SRAM X-SYNC Direct Mount Chainring for BOOST is built for riders running a single-ring drivetrain on a Boost-spaced setup — removing the spider entirely and mounting directly to the crank arm for a cleaner, lighter installation. The 3mm inboard offset is designed specifically for the 148x12mm Boost rear hub standard, keeping the chainline dialed where it needs to be.
What makes X-SYNC work as a 1x solution without a chain guide is the tooth profile itself. Alternating wide-narrow teeth engage with the inner and outer chain plates respectively, holding the chain on under the kind of rough, choppy terrain that would drop a conventional ring. The taller, squared tooth tops and mud-clearing recesses at the base keep things running through conditions where chain retention matters most. These rings mate with splined direct-mount crankarms secured by three bolts — if your crankset uses this interface, installation is straightforward.
