The 3mm inboard offset is designed specifically for the 148x12mm Boost rear hub standard, keeping the chainline dialed where it needs to be.\u003c\/p\u003e\n\n\u003cp\u003eWhat makes X-SYNC work as a 1x solution without a chain guide is the tooth profile itself. \u003cstrong\u003eAlternating wide-narrow teeth\u003c\/strong\u003e 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.\u003c\/p\u003e\n\n\u003ch3\u003eSRAM X-SYNC Direct Mount Chainring Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAvailable sizes:\u003c\/strong\u003e 28t, 34t\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOffset:\u003c\/strong\u003e 3mm inboard (Boost chainline)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Splined direct-mount crankarms with 3-bolt retention\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDesigned for:\u003c\/strong\u003e 10- and 11-speed chains in 1x drivetrain applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"SRAM","offers":[{"title":"28t \/ Black \/ 3mm","offer_id":43521116307500,"sku":"11.6218.018.016","price":120.0,"currency_code":"USD","in_stock":true},{"title":"34t \/ Black \/ 3mm","offer_id":43521116340268,"sku":"11.6218.018.019","price":120.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/sram-x-sync-direct-mount-chainring-for-boost-8315399.jpg?v=1771296556","url":"https:\/\/ricycles.com\/products\/sram-x-sync-direct-mount-chainring-for-boost","provider":"RA Cycles","version":"1.0","type":"link"}
