Product Description

PASS QUEST 104BCD Full-Profile Narrow-Wide MTB Chainring

The PASS QUEST 104BCD Full-Profile Narrow-Wide Chainring is designed for compatible 104BCD 4-bolt MTB cranksets, including selected Shimano XT and SLX setups.

CNC-machined from high-strength 7075-T651 aluminum alloy, it combines a clean full-profile design with a narrow-wide tooth profile for reliable chain retention, high rigidity and long-term durability.

Available in 32T, 34T, 36T, 38T and 40T, making it ideal for lightweight 1x MTB builds.

104BCD 4-Bolt Compatibility

Designed for compatible:

• Shimano XT 104BCD cranksets
• Shimano SLX 104BCD cranksets
• Other compatible 104BCD 4-bolt MTB cranks

Please confirm your crank uses a true 104BCD 4-bolt mounting pattern before ordering.

Narrow-Wide Tooth Design

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

This design helps improve drivetrain stability during:

• Climbing
• Rough terrain
• High-cadence riding
• Hard acceleration
• XC and trail riding

7075-T651 CNC Construction

The chainring is CNC-machined from 7075-T651 aluminum alloy.

This material provides an excellent balance of:

• High rigidity
• Low weight
• Wear resistance
• Impact resistance
• Long-term durability
• Direct power transfer

Full-Profile Design

The closed full-profile structure provides a cleaner, more integrated appearance compared with heavily skeletonized chainrings.

It also helps maintain structural rigidity under pedaling load.

Lightweight CNC Optimization

The chainring uses precision machining and chamfered details to remove unnecessary material without sacrificing stiffness.

This helps deliver:

• Reduced weight
• Stable power transfer
• Improved structural strength
• Premium CNC-machined appearance

Recessed Mounting Structure

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

This helps provide:

• Accurate positioning
• Secure installation
• Cleaner fitment
• Reduced unwanted movement
