Product Details

Overview & Technology

Strong, lightweight aluminum construction. The Truvativ 44T outer chainring (104mm BCD, 4-bolt) is built from precision-machined aluminum and finished in black anodize for long life and corrosion resistance. Designed specifically as an outer ring for 9-speed triple cranksets, it carries Truvativ's SRAM model ID CR-MLEG-104-A1 and integrates factory shift ramps to smooth front shifts under load. Real-world benefit: Riders get a reliable outer ring that blends low weight (approx. 0.1 lb) with the stiffness needed for efficient power transfer and repeatable front shifting across varied terrain.

Key Features

Ramped teeth and accurate profile. Both the middle and outer rings in this Truvativ family come with shift ramps tuned to 9-speed chain geometry, improving shift speed and reducing chain hang-ups. The 44-tooth outer profile is optimized for road-climbing and mixed-terrain rides where a higher gear range is needed. Robust hardware compatibility. 104mm BCD 4-bolt mounting ensures straightforward installation on compatible Truvativ and many 4-bolt cranksets that accept 104 BCD outer rings. The black anodized finish looks clean and resists wear from chain contact.

Fit & Compatibility

Exact specs: 44T, 104mm BCD, 4-bolt, outer position, designed for 9-speed chains. This ring is manufactured to fit triple chainring setups specified as 22/33/44 and mates with cranks that accept a 104mm 4-bolt outer ring. Compatibility notes: The ring is intended for 9-speed drivetrains — it will work best with 9-speed chains and front derailleurs set up for 9-speed geometry. While some users report cross-compatibility with 8-speed chains, it is not optimized for 10/11-speed spacing and may not provide ideal shifting with narrower chains or non-matching front derailleur ramps. Check your crank model and bolt type before purchasing.

Who It's For

This Truvativ outer chainring is ideal for mountain and touring riders running 9-speed triple drivetrains who need a reliable 44-tooth high gear. It's a straight replacement for worn or damaged outer rings on compatible Truvativ cranks or any crank accepting 104mm BCD 4-bolt outer rings. If you're rebuilding an older 9-speed drivetrain, upgrading from worn teeth, or swapping for a different gear ratio on a 22/33/44 triple, this ring provides a practical, cost-effective way to restore crisp front shifting and consistent chain retention.

Frequently Asked Questions

Will this chainring fit my crankset?

This ring fits cranksets that accept a 104mm BCD, 4-bolt outer chainring and are built for a 22/33/44 triple combination. Verify your crank's BCD and bolt pattern before purchase — if you're unsure, check your crank model or contact us with a photo and model number.

Is this ring compatible with 10- or 11-speed drivetrains?

The Truvativ 44T is designed for 9-speed chains and shift geometry. While some riders have success mixing adjacent chain speeds, it is not optimized for 10- or 11-speed chains due to different chain widths and ramp profiles, so we don't recommend it for those systems.

Can I replace only the outer ring when others are worn?

Yes — this is an outer position ring and can be replaced independently provided your crank uses a 4-bolt 104mm BCD outer ring and the middle/inner rings still match chainline and tooth spacing for smooth shifting.

What torque should I use for chainring bolts?

Typical chainring bolt torque ranges from about 8–12 Nm depending on bolt type. Always follow your crank manufacturer's torque spec when available and use a calibrated torque wrench to avoid over-tightening or thread damage.

Does this ring include chainring bolts?

No — the product listing describes the ring itself. Use your existing 4-bolt hardware if in good condition or purchase replacement bolts sized for your crank and chainring thickness.

How durable is the finish and material?

The ring is machined from high-grade aluminum and finished in black anodize, which offers good wear and corrosion resistance. With normal use the ramps and teeth hold up well; avoid heavy abuse (like grinding chain over damaged teeth) and inspect periodically for wear.

Buying Guide

When choosing a replacement chainring, confirm three key things: BCD (bolt circle diameter), number of bolts, and chain-speed compatibility. For 9-speed triples, 104mm BCD 4-bolt outer rings like this Truvativ 44T are common — but the middle and inner ring spacing must match to maintain crisp shifting. Consider tooth count changes only after checking chainline and derailleur capacity. Material matters: machined aluminum rings are light and stiff for efficient pedalling, while steel lasts longer under heavy wear. If your chain is worn, replace it with the ring to prolong ring life and preserve shifting performance.
