PASS QUEST 104BCD Narrow-Wide MTB Chainring

The PASS QUEST 104BCD Narrow-Wide Chainring is designed for compatible 104BCD MTB cranksets, including a wide range of Shimano and SRAM cranksets.

CNC-machined from high-strength aluminum alloy, it combines a lightweight open structure with an extended narrow-wide tooth profile for improved chain retention, rigidity and durability.

Ideal for riders building a clean and reliable 1x mountain bike drivetrain.

104BCD MTB Compatibility

Designed for compatible 104BCD 4-bolt MTB cranksets.

Shimano Compatible Cranks

Compatible with most Shimano 104BCD cranksets, including:

M390 / M430 / M4060 / M590 / M610 / M615 / M670 / M675 / M780 / M785 / M820 / M980

SRAM Compatible Cranks

Compatible with many SRAM 30mm spindle cranksets, including:

X0 / X9 / X7 / X5

Please confirm your crank model, 104BCD 4-bolt mounting pattern, and chainline before ordering.

Narrow-Wide Tooth Design

The chainring uses a narrow-wide tooth profile to improve chain engagement and reduce the chance of chain drop.

The tooth height reaches approximately:

8.5mm

The extended tooth design provides deeper chain engagement during:

• Rough terrain
• Climbing
• High-cadence riding
• Hard acceleration
• Technical MTB riding

Cross-Braced Hollow Structure

The chainring uses an optimized cross-braced hollow structure.

This design reduces unnecessary material while maintaining strength and rigidity around the load-bearing areas.

Benefits include:

• Lower weight
• Improved structural stiffness
• Better load distribution
• Stable pedaling feel

Recessed Bolt Interface

The recessed mounting structure increases the contact area between the chainring and crank interface.

This helps provide:

• More secure installation
• Better positioning
• Reduced fitment variation
• Cleaner overall appearance

CNC-Machined Lightweight Design

The chainring uses extensive CNC machining and chamfering to reduce weight while preserving structural rigidity.

Chamfered edges also improve the visual depth and give the chainring a more refined machined appearance.

High-Strength Aluminum Construction

The chainring is designed to provide a strong balance of:

• Rigidity
• Impact resistance
• Wear resistance
• Long-term durability
• Lightweight performance

Suitable for regular MTB use and 1x drivetrain conversions.
