What Our Gearhead® Experts Are Saying:
"Swapping chainrings on my race rig is easy thanks to the RIVAL X-SYNC Road Direct Mount. It’s light, stiff, and the X-SYNC tooth profile keeps my chain exactly where I want it—even when I hammer out of the saddle. Plus, the laser-etched finish still looks good after months of hard miles."
We’re always chasing that perfect balance between lightweight efficiency and race-day durability, and SRAM's RIVAL X-SYNC Road Direct Mount chainring delivers both. SRAM’s decades-long dedication to performance shines through in this sleek, laser-etched design that maintains its polished look even after heavy rides.
Thanks to the wide-tooth, narrow-tooth X-SYNC technology, the chain stays precisely where it should, no matter how hard we’re pushing. Whether we're fine-tuning our setups for time trials, triathlons, or fast-paced road races, the RIVAL X-SYNC offers rapid size swaps, smooth gear progression with X-Range tech, and improved aero performance.
