SRAM PowerLock™ – The Tool-Free Chain Quick Link for 10-Speed Drivetrains

The SRAM PowerLock™ is SRAM's original tool-free chain quick link — the fastest, most reliable way to connect, disconnect, and replace a 10-speed chain without a chain tool. Designed exclusively for SRAM 10-speed chains (PC 1090 and PC 1090R), the PowerLock installs in seconds by hand, locks securely under pedalling load, and is the OEM-specified connection method for SRAM's 10-speed chain range.

This pack contains 4 PowerLock quick links in black — enough for four chain installations, replacements, or emergency repairs. Whether you are a workshop mechanic stocking consumables, a rider who carries a spare link on every ride, or a home mechanic replacing a worn chain, the SRAM PowerLock 4-pack delivers exceptional value and peace of mind.

Important: The SRAM PowerLock is a single-use quick link. Once closed and ridden, it should not be reopened and reused. Always replace with a new PowerLock when removing the chain for cleaning or replacement.

Key Features

Tool-Free Installation: The PowerLock installs without any tools — thread the two link halves through the chain ends, bring the plates together, and apply pedalling force to lock the link securely. The entire process takes under 30 seconds. No chain tool, no master link pliers required for installation.
SRAM 10-Speed Compatibility: Designed and approved exclusively for SRAM 10-speed chains, specifically the PC 1090 and PC 1090R. The PowerLock is the OEM-specified connection method for these chains and ensures full compatibility with SRAM's 10-speed drivetrain systems (including X0, X9, X7, Rival, Force, and Red 10-speed groupsets).
Secure Locking Mechanism: The PowerLock's asymmetric plate design locks tighter under pedalling load — the harder you pedal, the more securely the link is held. This self-locking mechanism eliminates the risk of the link opening under load, making it as strong and reliable as a standard chain pin connection.
Single-Use Design for Maximum Safety: The PowerLock is engineered as a single-use link. The locking mechanism deforms slightly during the first closure to create a secure, permanent connection. Reopening and reusing the link compromises this mechanism and is not recommended by SRAM. Always use a new PowerLock when reinstalling the chain.
Black Finish: Stealthy black finish that blends with SRAM's black chain plates for a clean, integrated look on any 10-speed drivetrain.
Pack of 4: Four PowerLock quick links per pack — ideal for workshops, team mechanics, and riders who want a supply of spares for multiple chain changes or emergency repairs.
Lightweight: At just 12 grams per pack of 4, the PowerLock adds negligible weight. Carry one in your saddle bag or jersey pocket as a lightweight emergency repair option.

Frequently Asked Questions (FAQ)

What chains is the SRAM PowerLock compatible with?

The SRAM PowerLock 10-speed (this product) is compatible exclusively with SRAM 10-speed chains — specifically the PC 1090 and PC 1090R. It is not compatible with 9-speed, 11-speed, or 12-speed chains, nor with chains from other manufacturers (Shimano, KMC, etc.), which use different inner plate widths. Always match the PowerLock speed rating to your chain. SRAM offers PowerLock links for 9, 10, 11, and 12-speed chains separately.

How do I install the SRAM PowerLock?

Installation is tool-free and takes under 30 seconds. Thread one half of the PowerLock through each end of the chain (ensuring the chain ends are the correct inner/outer plate orientation). Bring the two link halves together so the pins seat in the slots. Hold the rear brake and apply firm pedalling force — this drives the plates together and locks the link. Confirm the link is fully locked by attempting to pull the plates apart by hand. The link should be completely secure with no movement.

Can I reuse the SRAM PowerLock after opening it?

No — the SRAM PowerLock is a single-use quick link. The locking mechanism works by deforming slightly during the first closure to create a secure, permanent connection. If you open the link (e.g., to remove the chain for cleaning), the locking mechanism is compromised and the link must be replaced with a new PowerLock. SRAM explicitly does not recommend reusing PowerLock links. This is why the 4-pack offers excellent value — you always have a fresh link ready for the next chain removal.

How do I open/remove the SRAM PowerLock?

To remove the PowerLock (and chain), you need master link pliers (also called quick link pliers or chain link pliers). These compress the link plates together to release the locking mechanism. Do not attempt to open the link with a screwdriver or by hand — this risks damaging the link, the chain, or injuring yourself. Once opened, discard the used PowerLock and install a new one when reinstalling the chain.

Is the PowerLock as strong as a standard chain pin?

Yes — when correctly installed, the SRAM PowerLock is as strong as a standard chain pin connection. The self-locking mechanism tightens under pedalling load, and SRAM designs the PowerLock to meet the same tensile strength requirements as the chain itself. The PowerLock is used by professional road and mountain bike racers worldwide and is the OEM-specified connection method for SRAM's 10-speed chains.

What SRAM groupsets use 10-speed chains compatible with this PowerLock?

SRAM 10-speed chains (PC 1090, PC 1090R) are used with the following SRAM 10-speed groupsets: Road: SRAM Red 10-speed, Force 10-speed, Rival 10-speed, Apex 10-speed. MTB: SRAM X0 10-speed, X9 10-speed, X7 10-speed, X5 10-speed. The PowerLock is the correct quick link for all of these groupsets when using SRAM chains.

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

No — the SRAM PowerLock is designed specifically for SRAM 10-speed chains and is not compatible with Shimano or KMC chains. Shimano 10-speed chains use a different inner plate width and require Shimano's own quick link (SM-CN900-10) or a compatible KMC Missing Link. Always use the quick link specified by your chain manufacturer to ensure correct fit and safety.

Should I carry a PowerLock as an emergency spare?

Yes — carrying a PowerLock quick link is one of the most practical emergency repair items for any cyclist. A broken chain is a common mechanical failure, and a PowerLock allows you to rejoin the chain and ride home without a chain tool. At just 3 grams per link, it adds negligible weight to your saddle bag or jersey pocket. With 4 links in this pack, keep one in your repair kit and store the rest at home for future chain changes.
