The X-SYNC profile alternates wide and narrow teeth to improve chain control while pedaling. Direct mounting on the crankset requires verification of the mounting interface, in addition to the desired tooth count.\u003c\/p\u003e\n\u003ch3\u003eX-SYNC tooth profile and laser-etched finish\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003eX-SYNC tooth profile\u003c\/strong\u003e uses tall teeth with squared edges, designed to engage the chain before traditional triangular profiles. The narrow profile and rounded chamfers help guide the chain when it is misaligned. The recesses help clear mud from the contact areas with inner links and rollers; the laser-etched finish is designed for greater durability.\u003c\/p\u003e\n\u003ch3\u003e8-bolt Direct Mount interface\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003e8-bolt Direct Mount\u003c\/strong\u003e fixing and the \u003cstrong\u003e6.5 mm offset\u003c\/strong\u003e are the key references to check for crankset compatibility.
