SRAM RED X-Sync 12/13 Speed Chainring – 8-Bolt Direct Mount Black Silver E1

SRAM RED X-Sync Chainrings: Precision Engineering for Elite Performance

For road cyclists chasing every second and triathletes demanding flawless efficiency, SRAM’s RED X-Sync Chainrings redefine what’s possible in drivetrain technology. Engineered with an ultra-lightweight yet rigid aluminum construction, these direct-mount chainrings deliver instant power transfer while minimizing rotational weight—a critical advantage during sprints or climbs. Their modular design lets you effortlessly swap between gear sizes (like 52/36T to 50/34T) to tailor your setup for any course challenge without tools or complicated adjustments.

Key Advantages Over Traditional Designs

Why Choose SRAM RED X-Sync?

The proprietary X-Sync tooth profile alternates narrow and wide teeth patterns to grip your chain securely during high-speed efforts or technical descents—eliminating slippage common with traditional setups that require frequent adjustments. This advanced retention technology ensures reliability whether you’re powering through mountain stages or maintaining pace on technical gravel routes.

A laser-etched surface treatment replaces older coatings, offering superior resistance against wear from constant pedaling forces—perfect for endurance athletes logging thousands of miles weekly on training loops or competitive events like century rides and gran fondos. Unlike standard finishes prone to cracking over time, SRAM’s design maintains precision even under extreme conditions.

Built with SRAM’s X-Range technology, these chainrings provide an extended gear spectrum while smoothing transitions between ratios—ideal for riders tackling mixed terrain or long-distance races where consistent cadence is critical. Unlike limited gear systems that leave gaps between ratios during climbs or sprints, RED X-Sync ensures seamless shifts every time you adjust your effort level.

Optimized for time trialists and triathletes competing at high speeds during events like Ironman races or UCI-sanctioned triathlons, their sleek profile cuts through air efficiently—saving watts compared to bulkier designs that slow you down on flat stages or long descents. Whether you’re racing against rivals or pushing personal bests on solo training runs, every gram saved here translates directly into faster times and reduced fatigue over distance.

Designed for those who demand precision without compromise—whether you’re fine-tuning gearing ahead of a criterium sprint finish or preparing for an all-day endurance challenge—SRAM’s RED X-Sync Chainrings deliver unmatched performance across disciplines while outclassing conventional systems in weight savings and durability metrics.
