SRAM X-Sync 2 Eagle Chainring 30T Black — Direct-Mount, 3mm Boost Offset for Quiet High-Retention Performance

The SRAM X-Sync 2 Eagle cold-forged 30T direct-mount chainring is a durable, quiet, high-retention chainring engineered for modern 1x Eagle drivetrains and Boost spacing.

This 30-tooth chainring uses SRAM's refined X-Sync 2 tooth profile and cold-forged aluminum construction to deliver better chain control, reduced noise and longer wear life. It’s built specifically for Eagle systems and Boost hub frames, with a 3mm offset for correct chainline on 141/148 Boost setups. The ring is a practical upgrade for riders who want a reliable, efficient front gear that integrates seamlessly with SRAM’s 12-speed ecosystems.

How does the X-Sync 2 tooth profile affect chain retention and noise?

The X-Sync 2 tooth geometry features longer, positive-rake teeth shaped to cradle the chain with greater accuracy. That profile reduces lateral movement, which means fewer dropped chains and quieter operation under load. You’ll notice smoother engagement and less mechanical clatter during rough, technical sections.

• Positive-rake teeth for firmer chain seating and improved retention
• Reduced lateral play lowers chain slap and audible noise
• Optimized for Eagle chains to improve wear patterns and longevity

What materials and manufacturing deliver durability without excess weight?

This chainring is cold forged from aluminum to combine structural strength with a modest weight penalty versus fully CNC-machined variants. Cold forging compresses the metal grain for improved fatigue resistance while keeping the ring lightweight and stiff. The black finish protects the surface and complements modern drivetrain aesthetics.

• Cold-forged aluminum for enhanced durability and stiffness
• Minimal weight increase (+~10g compared to full CNC models) for better longevity
• Protective black coating for corrosion resistance and appearance

Is this ring compatible with my drivetrain and frame spacing?

The 30T X-Sync 2 ring is designed for SRAM Eagle systems and works best with Eagle chains and 12-speed drivetrains. Its direct-mount interface fits compatible cranks and provides a clean, secure attachment without a BCD spider. The 3mm offset precisely sets the chainline for 141/148 Boost hub frames, so it’s ideal for modern Boost-compatible bikes.

• Optimized for Eagle chains and 12-speed systems
• Direct mount design — no traditional BCD required
• 3mm offset tuned for 141/148 Boost spacing and correct chainline

How will this chainring change on-trail performance?

Swapping to this X-Sync 2 ring improves pedaling efficiency and reduces drivetrain friction, which can make shifting and power transfer feel crisper. Better chain retention limits disruptions on technical climbs and bumpy descents, letting you focus on the trail. The quieter, longer-wearing tooth design keeps maintenance intervals longer and ride feedback more predictable.

• Improved pedaling efficiency with lower friction engagement
• Fewer dropped chains and more confidence on rough terrain
• Quieter drivetrain operation and extended service life

Who is this for? Riders running SRAM Eagle 12-speed drivetrains who ride Boost-spaced frames and want a dependable, long-lasting 30T direct-mount chainring will benefit most. It suits aggressive trail riders, enduro and all-mountain cyclists who need robust chain retention and a low-maintenance front gear. If you prioritize a system-engineered upgrade that pairs with Eagle chains and modern Boost geometry, this chainring is an efficient, durable choice.
