PASS QUEST Removable 104BCD Chainring Tooth Guard for Shimano MTB Cranks

Enhanced Tooth Protection. Lightweight Strength. Built for Aggressive Riding.

The PASS QUEST 104BCD Removable Chainring Tooth Guard is designed to protect your chainring teeth from accidental impacts, knocks, and external damage during demanding mountain bike riding.

Precision CNC-machined from high-strength 7075 aluminum alloy, this guard features a lightweight hollowed-out structure and a 5 mm thick construction for reliable structural support.

Positioned slightly higher than the chainring tooth tips, the protective guard helps absorb or deflect impacts before they reach the teeth. It also provides additional chain support, making it particularly suitable for riders who frequently perform jumps, drops, and technical riding maneuvers.

1. Removable Chainring Tooth Protection

The primary purpose of this guard is to protect your chainring teeth from external impacts.

The guard sits slightly higher than the tips of the chainring teeth, helping shield them from direct contact with rocks, obstacles, and other hard surfaces.

By reducing direct impacts on the tooth tips, the guard helps minimize damage and wear, extending the service life of your chainring.

Its removable design also allows convenient installation and removal when needed.

2. Designed for Aggressive MTB Riding

Built for riders who demand additional drivetrain protection during challenging riding conditions.

The protective guard is particularly suitable for:

• Mountain bikers riding on rough and technical trails.

• Riders who frequently perform jumps and drops.

• Riders who enjoy technical maneuvers and stunt riding.

• Riders looking to protect their chainring teeth from accidental impacts.

The guard also helps stabilize the chain by providing additional protection around the chainring.

3. High-Strength 7075 Aluminum Alloy

Manufactured from high-strength 7075 aluminum alloy using precision CNC machining.

The 5 mm thick construction provides reliable structural support while maintaining a carefully optimized weight.

The combination of high-strength material and precision machining delivers a durable protective component for demanding mountain bike applications.

4. Lightweight Hollowed-Out Construction

The guard features an optimized hollowed-out design to reduce unnecessary material while maintaining structural integrity.

The carefully machined striped details help balance weight reduction and rigidity.

The edges feature a refined 7-degree chamfer, creating a clean, three-dimensional appearance and a smooth surface finish.

5. Premium Matte Anodized Surface

7075 aluminum alloy presents challenges during the anodizing process.

Through multiple rounds of prototyping and surface-finishing improvements, we refined the anodizing process to achieve a premium matte anodized finish.

Compared with a conventional sandblasted finish, the refined matte surface provides a more attractive appearance while helping protect the aluminum against oxidation and everyday wear.

6. Precision Countersunk Mounting Structure

The precision-engineered countersunk structure helps position the mounting hardware accurately and provides a secure contact interface.

Its carefully designed mounting surfaces create a cleaner installation appearance and help reduce unwanted movement and noise when correctly installed.

7. Extended Mounting Bolts Included

The package includes extended silver steel mounting bolts designed for compatible double-chainring mounting configurations.

• Bolt Type: Extended Steel Mounting Bolts

• Bolt Length: 10 mm Extended Bolts

• Purpose: Provides additional mounting length for the specified installation arrangement.
