SRAM PC XX1 Eagle HollowPin Chain 12 Speed Copper - Durable Shift

In this review the SRAM PC XX1 Eagle HollowPin Chain is examined for riders who demand reliable, smooth shifting and long life from a 12-speed drivetrain. The bottom line: this chain is built to handle off-road abuse while maintaining precise shifting across SRAM Eagle cassettes, and its copper finish adds corrosion resistance and a distinctive look. For mountain bikers moving to a one-by 12-speed setup who want the specific engineering behind SRAM's narrower chain, this is a focused choice that balances weight, strength, and refinement.

Key Features

• 12 Speed Compatibility: Designed specifically for modern 12-speed Eagle drivetrains to deliver crisp, reliable shifts under load.
• HollowPin Construction: Hollow pins reduce rotating mass while preserving tensile strength for tough trail conditions.
• Precision Plate Forming: Plates are formed through an extensive multi-step process to achieve flatter profiles that improve chain engagement and shifting accuracy.
• Copper Finish: Corrosion-resistant copper plating offers durable protection and a distinctive aesthetic that stays visible over time.
• Long 126-Link Length: Supplied with 126 links and a PowerLock for easy installation and flexible sizing across frames and drivetrains.

Who It's For

This chain suits mountain bikers and off-road riders moving to SRAM Eagle 12-speed drivetrains who want a purpose-built chain from the same design family as SRAM cassettes. Riders who prioritize reliable shifting, reduced weight, and a durable finish will appreciate the HollowPin design and the manufacturing emphasis on flat, precisely formed plates.

Casual riders on single-speed or older drivetrains should look elsewhere for a more general-purpose chain, and those who need an ultra-low-cost replacement without the Copper finish or HollowPin weight savings may find simpler options meet their needs.

Pros & Cons

Pros

• High shifting precision on 12-speed Eagle drivetrains due to precisely formed plates.
• HollowPin design saves weight while retaining the tensile strength needed for off-road use.
• Copper plating adds corrosion resistance and a standout appearance on the bike.

Cons

• Specialized 12-speed design means it is not compatible with older multi-speed drivetrains.
