    Introducing the EK 520 SROZ2 O-Ring Clip Link (Single) (RAS) — a genuine EK replacement master link designed specifically for the EK 520 SROZ2 chain family. This single-link O-ring clip delivers a precise, easy-to-install connection that helps maintain smooth power transfer, optimal lubrication, and long-lasting performance across rides and seasons.

    Why this clip link matters


    • Precise compatibility with EK 520 SROZ2 chains ensures a reliable fit and consistent performance.
    • O-ring lubrication seal helps retain grease inside the rollers, reducing friction and wear in wet, muddy, or dusty conditions.
    • Secure clip design minimizes the risk of the link opening under high-torque loads during hard accelerations or steep climbs.
    • Compact, lightweight design makes on-bike maintenance quick and hassle-free when a replacement is needed.
    • Single-link convenience allows you to replace just the worn master link without disassembling or replacing the entire chain.

    Who is it for


    Ideal for riders using EK 520 SROZ2 chains who want a dependable, field-ready solution for chain repairs and maintenance—whether you’re a daily commuter, weekend warrior, or performance-focused cyclist.

    How to install


    1. Shift to the smallest chainring and smallest rear cog to relieve tension on the chain.
    2. If replacing an existing master link, detach the chain at the old link using a chain tool as needed.
    3. Align the EK 520 SROZ2 O-Ring Clip Link with the chain plates and seat the clip securely into place.
    4. Close the clip until it sits flush with the outer plate and check that the link moves freely without catching.
    5. Test your derailleur indexing and pedal a short distance to confirm the connection is solid.

    Care and longevity


    Keep the clip link clean and free of grit to protect the O-ring seal and preserve lubrication inside the rollers. After riding in rain or mud, wipe down the chain and re-lubricate as needed to maximize chain life and shift performance.
