Product Details

Overview & Technology

SRAM Red E1 1x DM brings SRAM's X-SYNC narrow-tooth / wide-tooth technology to road-focused 1x drivetrains. The ring is precision-machined from lightweight aluminum and finished with a hard-anodized surface for corrosion resistance and long wear life. The X-SYNC profile alternates narrow and wide teeth to capture the chain on every revolution, minimizing drop and noise compared with conventional tooth shapes. The ring is built for modern 12-speed FlatTop chains and features SRAM's direct-mount 8-bolt interface for a clean, stiff connection to compatible cranksets. Model ID CR-XSNC-DM-E1 and Manufacturer Part #00.6218.060.000 identify this ring in SRAM's line-up — a compact, weight-conscious upgrade for riders choosing a single-ring setup.

Key Features & Real-World Benefits

X-SYNC narrow/wide teeth: Maximum chain control under load means fewer dropped chains and reliable shifting with wide-range cassettes. In practice this translates to more confidence on sprints, attacks and rough pavement where chain stability matters. • Direct Mount (SRAM 8-bolt): Reduced stack height, improved stiffness, and simpler installation compared with spider-mounted rings. • Optimized for 12-speed FlatTop chains: Precise tooth geometry reduces noise and wear when paired with SRAM 12-speed systems. • Available 38–46T: Choose tighter gearing for fast road spins or larger rings for higher top speeds and longer gravel descents.

Fit, Compatibility & Installation Notes

The Red E1 1x DM is a SRAM direct-mount chainring with an 8-bolt interface — designed to fit SRAM cranks that accept the Direct Mount SRAM 8 Bolt pattern. It is optimized for SRAM 12-speed FlatTop chains and the Red/Apex/Force family of road 12-speed drivetrains, though physically it will work with most 12-speed chains that match the FlatTop profile. Installation is straightforward: align the ring to the crank's direct mount spline pattern and torque bolts to the crank manufacturer's specification. For best performance, use fresh chainring bolts or the correct SRAM-supplied fasteners and check chainline after install. If you're switching from a double to a 1x setup, confirm derailleur and cassette gearing provide the range you need before finalizing chainring size.

Who It's For

This ring is aimed at road and gravel riders who want the simplicity and reliability of a 1x drivetrain without compromising the high-performance cues of SRAM's Red family. Racers who favor a lightweight, low-drag cockpit and riders converting from a double to 1x for cleaner shifting and fewer mechanicals will appreciate the Red E1. It's also a smart upgrade for weight-conscious athletes and bikepackers seeking dependable chain retention across varied terrain. Choose a smaller tooth count for hillier courses or larger sizes for flatter, higher-speed riding.

Frequently Asked Questions

Is this chainring compatible with my SRAM 12-speed crank?

Yes — the Red E1 1x DM uses SRAM's Direct Mount 8-bolt interface and is compatible with SRAM cranks that accept that direct-mount pattern. Confirm your crank explicitly lists support for SRAM 8-bolt direct-mount rings before purchasing.

Can I use this with Shimano drivetrains?

While the physical mount and tooth profile are optimized for SRAM 12-speed FlatTop chains and drivetrains, the ring can work with other 12-speed systems in many cases. Expect best performance when paired with SRAM FlatTop chains and AXS components due to matched tooth geometry.

Which tooth count should I choose for my riding?

Choose smaller sizes (38–40T) for climbing-focused routes or mixed-terrain gravel where lower gears help; mid-range sizes (42–44T) suit most road and fast gravel use; a 46T favors high-speed road events and flatter courses. Consider cassette range and expected cadence when selecting.

Does this chainring reduce chain drops without a chain guide?

Yes — the X-SYNC narrow/wide profiling is designed to increase chain retention and significantly reduce the likelihood of chain drops under normal riding conditions, often removing the need for a dedicated chain guide on 1x setups.

What maintenance will keep the ring working well?

Keep the ring clean of grit and debris, maintain proper chain lubrication, and replace the chain as it wears to prevent premature tooth wear. Inspect mounting bolts for correct torque after the first rides and periodically thereafter.

What is the exact weight and shipping size?

SRAM lists the shipping weight at approximately 0.35 lb with packing dimensions of 7.1" x 7.2" x 0.9". Actual in-use weight will be slightly lower when removed from packaging.

Buying Guide

When choosing a 1x direct-mount chainring, match the BCD/mounting interface first — the Red E1 uses SRAM's DM 8-bolt standard — then confirm chain compatibility (this ring is optimized for SRAM 12-speed FlatTop chains). Pick a tooth count that balances your climbing ability and desired top speed; smaller rings give lower gears for hills while larger rings increase top-end speed. Also consider material and finish: anodized aluminum offers an excellent weight-to-durability ratio for road and gravel use. Finally, factor in drivetrain ecosystem: for quiet, long-lasting performance use matched SRAM components (chain, cassette, derailleur) whenever possible.
