Product Details

Overview & Technology

SRAM 11.6218.000.001 is a purpose-built 39T inner chainring made for 10-speed road doubles that use a 130mm, 5-bolt BCD. As an OEM replacement for the Red 2012 family (model ID CR-XGLD-130-A1), it restores original shifting performance and ride feel when your inner ring is worn, bent or damaged. The ring is CNC-machined from high-grade aluminum and finished in a durable black anodize for corrosion resistance and longevity. Its tooth profile and ramping are engineered to match SRAM's front shifting geometry for crisp, reliable shifts under load — a real-world benefit on fast group rides and long training days.

Key Features

Precision construction: CNC-machined aluminum body keeps weight low while maintaining tooth stiffness for consistent power transfer. The black anodized surface resists abrasion and road grime. Fit & shifting optimized: 39 teeth, designed as the inner ring for 39/53 doubles with 130mm 5-bolt BCD. Tooth ramps and profiles are matched to SRAM's 10-speed chain specifications so front shifts remain predictable and fast. • 39T inner ring — compatible with 39/53 cranksets • 5-bolt, 130mm BCD — fits standard road double spiders • Aluminum construction with black anodized finish — light and durable • Designed for 10-speed chains and SRAM Red 2012 systems

Fit, Compatibility & Installation

This chainring is built for 5-bolt 130mm BCD cranksets and specified as the inner ring for 39/53 setups. Confirm your crank spider uses the 130mm bolt circle and that your drivetrain is 10-speed before ordering. The listed Manufacturer Part # is 11.6218.000.001 (SRAM Model ID CR-XGLD-130-A1) and Forest Bikes SKU 390602. Installation is straightforward: use appropriate chainring bolts, torque to the crankmaker's recommended specification, and inspect front derailleur height and limit screws after fitting. If your chain or outer ring is severely worn, replace them to maintain shifting precision and chain life.

Who This Chainring Is For

Road cyclists running SRAM 10-speed double cranksets — especially owners of 2012-era Red groupsets — will find this ring an exact-form replacement that preserves original shifting characteristics. It's aimed at riders who value lightweight, OEM-spec parts and want a drop-in solution to restore crisp front shifts. Suitable for club racers, long-distance road riders and mechanics servicing older SRAM cranksets. If you ride with modern 11/12-speed chains, expect possible minor shifting compromises; match the ring to your chain speed when possible.

Frequently Asked Questions

Will this chainring fit my crankset?

This ring fits 5-bolt crank spiders with a 130mm bolt circle diameter and is intended as the inner ring for 39/53 doubles. Verify your crank's BCD before purchase. If your crank uses a different BCD or bolt pattern, this ring will not mount.

Is this chainring compatible with 11-speed chains?

The ring is specified for 10-speed chains and has tooth profiles tuned for SRAM's 10-speed front shifting. An 11-speed chain may work physically, but shifting may not be as precise. For best results, match chainring and chain speed.

Do I need to replace the outer ring or chain at the same time?

You don't have to replace the outer ring, but replacing a worn outer ring or stretched chain at the same time will restore optimal shift quality and reduce accelerated wear. If the chain shows visible stretch, fit a new chain when installing a new ring.

What tools and torque settings are required for installation?

Use proper chainring bolts and a torque wrench. Torque specs vary by crank manufacturer — typically 8–12 Nm for chainring bolts on road cranks. Always consult your crankmaker's recommended torque and follow correct tightening sequence.

Is the finish durable and corrosion-resistant?

Yes — the ring is anodized black to improve corrosion resistance and surface hardness. While durable, avoid harsh chemicals and inspect for wear periodically if you ride in wet or salty conditions.

What are the shipping size and weight?

Shipping dimensions are approximately 6.8" x 7" x 0.1" and the listed weight is 0.05 lb, making it a compact, lightweight replacement part.

Buying Guide

When choosing a replacement chainring, match three things first: bolt circle diameter (BCD), tooth count (T), and the number of speeds your drivetrain uses. A 130mm BCD 5-bolt ring is common for road doubles, but crank standards vary, so measure or check your crank's documentation before ordering. Material and machining affect feel and longevity. CNC-machined aluminum rings like this SRAM unit balance low weight with tooth stiffness for efficient power transfer. If you ride in corrosive conditions or prioritize longevity, look for anodized finishes and replace worn rings and chains together to maintain shifting performance.
