Product Details

Overview & Technology

SRAM X-Sync 2 is a cold-forged, direct-mount chainring engineered for modern 12-speed 1x mountain drivetrains. Built around SRAM's proven X-Sync 2 narrow-wide tooth profile, this chainring is optimized for fast chain pickup, quiet running and excellent chain retention across rough terrain. The CR-XSNC-DM-B1 (Mfg. P/N 11.6218.030.240, Forest Product #391068) uses a direct-mount 3-bolt SRAM interface and is available in 30T, 32T and 34T tooth counts with either a 3mm or 6mm offset. Cold forging increases material density and fatigue resistance compared with machining alone, delivering a slim, stiff ring that resists wear while keeping weight low (shipping weight ~0.2 lb / ~90 g).

Key Features & Benefits

Precision tooth geometry: X-Sync 2's narrow-wide alternating tooth widths and optimized ramping pick up the chain instantly and reduce drop risk — especially useful on techy, bumpy climbs and rough descents. Cold-forged aluminum construction: The cold-forged aluminum body provides a high strength-to-weight ratio and improved fatigue life vs. standard pressed rings. The black anodized finish helps corrosion resistance and gives a clean, stealth look on any SRAM-compatible crank.

Fit, Compatibility & Installation

The ring uses a SRAM direct-mount 3-bolt interface and is intended for SRAM 12-speed 1x drivetrains. Available offsets (3mm and 6mm) let you dial chainline to match boost/non-boost frames and wide-range cassettes; choose the offset required by your crank and frame specs. The X-Sync 2 rings are designed for 12-speed chains — best performance is achieved with SRAM Eagle 12-speed chains, though other modern 12-speed chains with compatible widths will generally work. Installation should follow your crank manufacturer's torque specs for direct-mount hardware. Because the ring is cold-forged aluminum, avoid over-torquing and inspect bolts periodically for tightness. If you run a bash/guide or bashless set-up, confirm clearances for your selected tooth count and offset.

Who This Chainring Is For

This chainring is aimed at mountain riders who want reliable chain security and lightweight performance on 1x 12-speed bikes — from aggressive trail riders to cross-country racers who prioritize crisp chain pickup and minimal weight. It's an ideal replacement ring for worn stock rings or an upgrade for riders moving to a narrow-wide 1x setup. Choose lower tooth counts (30T) for steep climbs and better acceleration, mid-range (32T) for balanced trail performance, and 34T for higher top-end speed. The 3mm and 6mm offset options make it a flexible choice across a wide range of cranksets and frame chainlines.

Frequently Asked Questions

Will this ring fit my crank?

The X-Sync 2 chainring uses SRAM's direct-mount 3-bolt interface. It will fit cranksets that accept SRAM direct-mount rings; verify your crank manual or manufacturer specs to confirm compatibility with SRAM direct-mount 3-bolt rings and choose the correct offset for your chainline.

Can I use this with non-SRAM 12-speed chains?

Yes — the ring is designed for 12-speed chain widths and will generally work with other modern 12-speed chains. For best shifting and retention performance we recommend pairing it with SRAM Eagle 12-speed chains.

How do I choose between the 3mm and 6mm offset?

Offset choice depends on your crank and frame chainline. Use your crank manufacturer's recommended chainline or consult your frame spec: 3mm suits many boost setups, while 6mm moves the ring further outboard for some non-standard cranks or wider cassettes. When in doubt, check the crank/chainline documentation or ask our tech team.

What's the expected weight and durability?

The ring ships at approximately 0.2 lb (~90 g). Cold forging increases material density and fatigue resistance versus stamped rings, so you get a durable part that resists wear while remaining lightweight. Actual service life depends on riding conditions, chain maintenance and frequency of use.

Can I run a bash guard or chain guide with this ring?

In most cases yes, but clearance depends on tooth count, offset and your frame's chainstay/guide mount geometry. Lower tooth counts and certain offsets may have less room for bash guards — measure carefully or consult your guide's manufacturer compatibility chart before installing.

Do I need special tools to install the direct-mount ring?

No special chainring tools are required beyond the correct bit/socket for your crank's direct-mount bolts and a calibrated torque wrench. Always tighten to the crank manufacturer's specified torque to avoid damage or loosening.

Buying Guide

When buying a direct-mount chainring, prioritise compatibility: confirm your crank's direct-mount standard (SRAM 3-bolt), the required offset for correct chainline, and the tooth count that matches your riding terrain. Tooth count changes acceleration and top speed — smaller rings give easier climbing, larger rings increase top-end speed. Material and construction matter: cold-forged aluminum offers a strong, lightweight option that resists wear better than stamped rings. Finally, ensure you pair the ring with a modern 12-speed chain (SRAM Eagle or equivalent) and follow torque specs during installation for reliable long-term performance.
