SRAM X-Sync 2 34T Chainring Black — Direct-Mount Cold-Forged Durability, 3mm Boost Offset

The SRAM X-Sync 2 Eagle Cold Forged 34T Direct Mount Chainring is a durable, cold-forged aluminum 34-tooth direct-mount ring with Eagle tooth profiling and a 3mm boost offset for 141/148 Boost hub setups.

This chainring blends SRAM's X-Sync 2 tooth geometry with cold-forged aluminum construction to deliver improved chain retention, lower noise, and long-lasting service life. Built for single-chainring drivetrains, it fits a wide range of modern mountain bikes and is compatible with 10-, 11- and 12-speed systems while keeping weight and budget trade-offs in check compared to fully CNC-machined options.

How does the X-Sync 2 tooth profile help on rough trails?

SRAM's Eagle-inspired tooth shaping is designed to guide and hold the chain securely even when hitting roots, rocks, or hard impacts. The alternating narrow-wide layout combined with ramped shapes reduces the chance of drops and keeps shifts crisp under load.

• Alternating narrow-wide teeth for positive chain engagement
• Profiled ramps that smooth chain pickup during pedaling
• Reduced chain slap and quieter operation on rough terrain

What are the material and weight trade-offs of the cold-forged construction?

Cold forging compresses aluminum for a stronger grain structure than some stamped alternatives, providing a robust ring at a modest price and weight. Compared to fully CNC-machined versions, this ring adds about +10 g while retaining high strength and wear resistance.

• Cold-forged aluminum for improved durability and cost-efficiency
• Approximately +10 g heavier than CNC-machined counterparts
• Black finish that resists corrosion and integrates visually with most drivetrains

Is this chainring compatible with my bike and drivetrain?

This is a direct-mount 34T ring with a 3mm offset engineered for Boost spacing, compatible with 141 mm and 148 mm Boost hub platforms. It works across 10-, 11-, and 12-speed chains when used in single-chainring Eagle-style setups, but check your crank interface for direct-mount fitment.

• 34-tooth direct-mount design for single-chainring drivetrains
• 3 mm offset specifically for 141/148 Boost hub chainline correction
• Compatible with 10/11/12-speed chains; confirm crank direct-mount standard

How easy is installation and maintenance?

Installation is straightforward — swap the direct-mount ring onto a compatible SRAM or direct-mount crank using standard tools. Routine maintenance is the same as other chainrings: keep the chain clean and replace the ring when tooth wear affects shifting or retention.

• Direct-mount fit reduces installation steps and hardware
• Routine chain cleaning and correct chainline prolongs life
• Replace when hooked or worn teeth impair shifting or retention

Who is this for: The SRAM X-Sync 2 Eagle Cold Forged 34T is aimed at mountain bikers who want a reliable, high-retention single-ring setup without the premium cost of fully CNC-machined rings. It suits trail, enduro, and gravel riders using Boost-spaced frames (141/148) who run 10–12-speed drivetrains and value durability, quieter operation, and predictable chain control on technical terrain.
