Product Details

Overview & Technology

SRAM GX Eagle T‑Type DM is a purpose‑built chainring for modern 12‑speed Eagle Transmission drivetrains that require T‑Type chains. Machined from lightweight aluminum and finished in grey, the ring uses a direct‑mount SRAM 8‑bolt interface for a clean, stiff connection to compatible cranksets. The ring features a precision narrow‑wide tooth profile and tooth timing tuned for T‑Type chain geometry. That combination delivers superior chain retention, quieter pedaling and crisper shifts compared with generic aftermarket rings — especially under the high torque and rough terrain conditions mountain riders expect.

Key Features & Construction

The GX Eagle T‑Type DM pairs proven materials with targeted engineering to deliver reliable trail performance: • Material: 6061‑grade aluminum (machined) for a high strength‑to‑weight ratio. • Narrow‑wide tooth profile: Optimized for T‑Type chains to reduce drops and improve engagement. • Direct‑mount 8‑bolt: SRAM SRAM 8‑bolt DM interface for stiff, tool‑friendly installation. • 12‑speed compatibility: Specifically manufactured for SRAM Eagle Transmission 12‑speed T‑Type chains. Lightweight construction (approx. 0.2 lb) keeps rotational mass low while the machined tooth ramps and timing help maintain crisp front shifting and controlled chain pickup when swapping sizes between 30, 32 and 34 teeth.

Fit, Compatibility & Specs

This chainring is built to the SRAM direct‑mount 8‑bolt standard and is compatible with SRAM Eagle Transmission systems that require a T‑Type chainring. Confirm your crank uses SRAM's 8‑bolt direct mount interface before ordering. Technical specs at a glance: Teeth: 30 / 32 / 34 options. Speed: 12. Material: Aluminum. Manufacturer Part #: 11.6218.054.000. SRAM Model ID: CR‑TTYP‑DM‑D1. Shipping dims: 6" x 0.25" x 6"; Weight: 0.2 lb. • Designed specifically for T‑Type chains — avoid mixing with non‑T‑Type chain standards. • Direct mount only — not compatible with traditional 5‑bolt or BCD spider adapters.

Who It's For

This ring is ideal for mountain riders running a SRAM Eagle Transmission 12‑speed drivetrain who want a lightweight, durable direct‑mount option tuned for T‑Type chains. Trail, all‑mountain and enduro riders who prioritize chain retention and minimal drivetrain noise will see the most benefit. Choose a 30T for steep technical climbs and maximum clearance, a 32T for an all‑around gear ratio, or a 34T if you favor higher top‑end speed on faster trails and cross‑country terrain. It's a direct swap for compatible SRAM cranks and a smart upgrade when moving to a T‑Type chain system.

Frequently Asked Questions

Will this fit my crankset?

The GX Eagle T‑Type DM uses SRAM's direct‑mount 8‑bolt interface. It will fit cranksets that accept the SRAM 8‑bolt direct‑mount pattern. Check your crank's mounting standard — if it uses a different BCD or bolt pattern, this ring will not be compatible.

Can I use a standard Eagle chain with this T‑Type ring?

This ring is engineered specifically for T‑Type (Eagle Transmission) chains. Using a standard, non‑T‑Type Eagle chain may reduce shifting precision and accelerate wear. For best performance and warranty compliance, pair the ring with a T‑Type chain.

How do I choose between 30, 32 and 34 teeth?

Choose based on terrain and cadence: 30T for steep, technical climbs and more clearance; 32T for versatile trail use; 34T for higher top speeds on fast, flowing trails. Also consider rear cassette range and your preferred cadence when selecting tooth count.

What torque is required for installation?

Follow your crank manufacturer's recommended torque for direct‑mount chainrings — typically in the range specified for SRAM 8‑bolt interfaces. Use a calibrated torque wrench and thread locker if recommended by the crank maker to ensure safe installation.

How long will the chainring last?

Lifespan depends on riding conditions, maintenance, and chain wear. With a matched T‑Type chain and regular chain maintenance (cleaning and lubrication), an aluminum ring should provide long, reliable service. Replace the ring when shifting degrades or teeth show pronounced wear or shark‑toothing.

Can I run this on an e‑MTB?

Yes, the ring can be used on compatible 12‑speed e‑MTBs that use the SRAM 8‑bolt direct‑mount standard and T‑Type chains. Keep in mind e‑MTB use can accelerate wear due to higher torque, so monitor chain and ring condition more frequently.

Buying Guide

When choosing a direct‑mount chainring for your SRAM Eagle Transmission drivetrain, prioritize compatibility (T‑Type chain and SRAM 8‑bolt DM interface), desired gearing, and material. Aluminum rings like the GX Eagle T‑Type DM offer an excellent mix of light weight and durability for trail riders who want predictable shifts and low rotating mass. Match tooth count to your terrain and cadence goals: smaller rings for steep climbs and maximum clearance, larger rings for speed. Also buy a T‑Type chain at the same time — the ring and chain are engineered as a system for best longevity and performance.
