Product Details

Overview & Technology

Truvativ's 44T 9-speed 104mm BCD outer chainring is a purpose-built replacement for 3x crank systems that use a 104mm 4-bolt pattern. Machined from high-grade aluminum and finished in hard-wearing black, this ring balances weight and durability to keep your drivetrain shifting cleanly mile after mile. The ring follows SRAM/Truvativ spacing and tooth profiling for 9-speed chains (SRAM model ID CR-MLEG-104-A1 / MPN 11.6215.186.000), so it restores original shifting performance on compatible cranksets. The precision-tooth machining reduces chain drag and helps prevent drop-offs under load — a practical upgrade if your outer ring is worn, bent, or missing.

Key Features & Construction

Material and build: CNC-machined aluminum gives an excellent strength-to-weight ratio, resisting deformation under pedal loads while keeping mass low (0.3 lb shipping weight). The 4-bolt, 104 BCD design is a widely used standard for mountain and touring triples. Real-world benefits: The tooth profile is optimized for 9-speed chains, improving engagement and shifting reliability across the 22/33/44 cassette pairing. A black anodized finish protects against corrosion and abrasion from rocks, mud, and chain wear.

Fit, Compatibility & Installation

This chainring fits 104mm BCD, 4-bolt crank spiders and is specified as the outer ring for 22/33/44 triple configurations. Confirm your crank uses a 104 BCD outer position and is intended for a 9-speed chain before purchase. The part number 11.6215.186.000 and SRAM ID CR-MLEG-104-A1 are useful references when cross-checking fit. Installation is straightforward: remove crank bolts, swap the worn ring for the Truvativ 44T, torque to the manufacturer's spec and run through the gears to verify indexing. Use quality chainring bolts and check front derailleur height and limit screws if shifting needs slight adjustment.

Who This Chainring Is For

This ring is ideal for mountain cyclists, commuters and bikepackers running vintage or modern 3x 9-speed drivetrains who need a reliable outer chainring replacement. It's a practical choice for riders restoring older bikes, maintaining workshop stock, or keeping a trusted trail bike running during seasons of heavy use. If you ride mixed terrain and depend on a wide-range triple for steep climbs and loaded touring, this ring gives predictable shifting and long service life without the premium price of exotic materials.

Frequently Asked Questions

Will this ring fit my crankset?

This Truvativ 44T ring fits 104mm BCD, 4-bolt cranks and is specified as the outer ring for 22/33/44 triples. Verify your crank spider measures 104mm BCD and that your crank is intended for a 9-speed outer chainring before buying.

Is this chainring compatible with 10- or 8-speed chains?

It's profiled for 9-speed chains, so it works best with 9-speed drivetrains. In practice a 10- or 8-speed chain may physically fit but could result in suboptimal shifting. For best performance match the chainring to your chain speed.

Do I need new chainring bolts to install this?

You can reuse quality bolts if they are in good condition, but we recommend replacing corroded or stretched bolts during installation. Use the correct length and torque specified by your crank manufacturer to avoid damage.

How durable is the aluminum finish?

The ring's black anodized finish protects the aluminum from corrosion and surface wear, but heavy abuse (rocks, heavy grinding) will still show wear over time. Periodic inspection and timely replacement keeps drivetrain performance reliable.

Can I use this ring on a single-ring conversion?

While mechanically possible if you adapt your crank, this ring is cut as an outer ring for a triple setup. For a single-ring conversion you may prefer a dedicated narrow-wide or single-specific ring to improve chain security.

What tools are required for installation?

Basic tools: crank removal tool appropriate to your crankset, hex/torx for chainring bolts, torque wrench for proper tightening, and front derailleur adjustment tools (screwdriver, pliers). Follow your crank and drivetrain manufacturer's torque specs.

Buying Guide

When replacing an outer chainring, prioritize correct BCD, tooth count and chain-speed compatibility. For 9-speed triples, a 104mm 4-bolt outer ring with matching tooth profile restores intended chainline and shifting. Check for excessive wear on chain, cassette and chainrings — replacing a worn chain with a new ring may cause accelerated wear. If you're converting to a single-ring setup or using a different chain speed, consider ring-specific options (narrow-wide, 10/11-speed profiles) instead of a direct-triple replacement. For routine trail maintenance, keeping a spare 44T 104 BCD ring in your toolkit is a smart, lightweight solution to get you back on the trail fast.
