SRAM PowerLock XX1 – The Professional Chain Quick Link for 11-Speed Drivetrains

The SRAM PowerLock XX1 is SRAM’s premium quick-link chain connector, designed specifically for 11-speed chains in the XX1 Eagle and compatible drivetrains. Whether you’re doing a chain swap in the workshop or a trailside repair, the PowerLock delivers a secure, tool-free connection that meets the demands of high-performance MTB riding.

This pack contains 4 PowerLock connectors — enough for multiple chain installations or to keep spares in your trail kit, workshop, and bike bag simultaneously. Each connector is single-use by design: once locked, it cannot be reopened without tools, ensuring maximum security under load.

Frequently Asked Questions (FAQ)

What is a PowerLock chain connector and how does it work?

A PowerLock is SRAM’s quick-link master link for bicycle chains. It consists of two outer plates with pins that snap together to join the two ends of a chain. To close it, align the two halves, push them together, and apply pedal pressure — the link locks itself under load. No tools are required to install it. However, once locked, it cannot be reopened without a chain tool or link pliers.

Is the SRAM PowerLock reusable?

No. The SRAM PowerLock is a single-use connector. Once it has been locked and ridden, the locking mechanism deforms slightly under load, making it unsafe to reuse. If you need to remove your chain (e.g. for cleaning or replacement), you should use a new PowerLock to reconnect it. This is why buying a multi-pack is strongly recommended for regular maintenance.

Which chains and drivetrains is the XX1 PowerLock compatible with?

The PowerLock XX1 is designed for SRAM 11-speed chains, including the XX1, X01, GX Eagle (11-speed), and other SRAM 11-speed chains. It is not compatible with 10-speed, 12-speed, or other brand chains — always match the PowerLock speed rating to your chain. When in doubt, check the chain’s packaging or SRAM’s compatibility chart.

Can I use the SRAM PowerLock with a Shimano or KMC chain?

SRAM PowerLock connectors are engineered specifically for SRAM chains. While some riders use them with compatible third-party chains of the same speed rating, this is not officially supported by SRAM. For guaranteed compatibility and safety, use the PowerLock with the corresponding SRAM chain. KMC and Shimano offer their own master links (Missing Link, Quick Link) for their respective chains.

How do I install the SRAM PowerLock?

1. Thread the chain through your drivetrain (derailleur, chainring, cassette). 2. Hold the two chain ends together. 3. Insert the PowerLock pins into the chain end links from the outside. 4. Push the two halves together until they click. 5. Apply firm pedal pressure (or pull the chain taut by hand) to fully seat and lock the connector. The link is now locked and ready to ride. Do not attempt to open it again without a chain tool or link pliers.

How do I remove the SRAM PowerLock if needed?

To remove a PowerLock, you need a chain link pliers (also called master link pliers) or a standard chain tool. Compress the two plates toward each other to release the locking mechanism, then pull the halves apart. Because the connector is single-use, discard it after removal and use a new PowerLock when reconnecting the chain.

Why does this pack contain 4 connectors?

Four connectors is the standard trade pack size for the SRAM PowerLock. Since each connector is single-use, having multiple on hand is practical for: workshop stock (multiple bike services), carrying a spare on trail rides, replacing the connector after each deep clean, and keeping one in your saddle bag for emergency repairs. Buying in a 4-pack is significantly more cost-effective than purchasing individually.

What is the weight of the PowerLock XX1?

The total weight of the 4-piece set is 12 g, meaning each individual connector weighs approximately 3 g. This makes it one of the lightest chain joining solutions available, consistent with the XX1’s weight-optimised design philosophy.

Is the PowerLock XX1 suitable for e-bikes?

Yes, provided your e-bike uses an 11-speed SRAM chain. The PowerLock is rated for the torque loads of standard MTB drivetrains. For high-torque mid-drive e-bikes, ensure your chain and connector are rated for e-bike use — check SRAM’s current e-bike compatibility guidelines for your specific drivetrain.

What is the difference between PowerLock and PowerLink?

PowerLock is SRAM’s single-use connector — it locks permanently under load and cannot be reopened without tools. PowerLink is SRAM’s reusable quick-link, designed for chains up to 10-speed, which can be opened and closed by hand multiple times. For 11-speed and 12-speed chains, SRAM uses PowerLock exclusively, as the narrower chain pitch requires a more secure locking mechanism.
