Concept2 Rower Bungee Cord Replacement: 3 Simple Steps

Replacing the bungee cord on a Concept2 Rower restores optimal handle retraction and rowing performance. This essential maintenance task can be completed at home using basic tools like a 5/32 inch hex wrench and a genuine Concept2 shock cord, typically taking less than an hour for most users. A worn cord causes sluggish handle return, impacting workout efficiency and potentially damaging other machine parts.

Understanding Your Concept2 Rower’s Bungee Cord

The bungee cord, also known as a shock cord, is a critical component in Concept2 Indoor Rower models C, D, and E. Its primary function is to retract the handle and chain smoothly during the recovery phase of each stroke, ensuring consistent tension for the next drive. Without a properly functioning bungee cord, the chain may recoil slowly or not at all, disrupting rhythm and compromising workout effectiveness.

Signs of a worn-out bungee cord include a handle that retracts sluggishly, requires manual assistance to return fully, or shows visible fraying, thinning, or breakage. Users might also find small rubber strands or debris, indicating internal damage to the cord’s elasticity. Addressing these issues promptly improves the rowing experience and prevents potential damage to other machine parts by maintaining proper chain tension.

Essential Tools and Replacement Parts

Before beginning the replacement process, gather the necessary tools and ensure you have the correct Concept2 replacement shock cord for a smoother procedure.

Tools You’ll Need:

• Hex Wrench: Typically a 5/32 inch hex wrench (or a 4 mm hex wrench).
• Combination Wrench: Often a 7/16 inch (or 11 mm) combination wrench.
• T27 6-lobe driver: Some models may require this for certain fasteners.

Replacement Part:

• Concept2 Shock Cord (Bungee Cord): It is highly recommended to purchase a genuine Concept2 shock cord. These are specifically designed for your rower’s model (C, D, or E) and ensure proper length, durability, and performance. You can typically find these on the Concept2 website or by contacting their customer support. While the cost is relatively low, the impact on your rower’s functionality is substantial.

Using an authentic Concept2 part is crucial for ensuring compatibility and maintaining the integrity of your machine. Generic cords may not provide the correct tension or withstand the repeated stress of rowing, leading to premature wear or potential safety issues.

Step-by-Step Guide: Replacing Your Concept2 Bungee Cord

Replacing the bungee cord on your Concept2 Rower is a manageable task if you follow these steps carefully. The process involves some disassembly and careful routing to ensure proper function.

Preparation and Disassembly

1. Separate the Rower: Begin by separating the monorail (the part with the seat) from the flywheel end of the rower. Lift the monorail and raise it upwards, allowing the two sections to disconnect. This provides better access to the bungee mechanism.
2. Flip the Frame: Carefully flip the flywheel end of the frame upside down. This position exposes the underside where the bungee cord and its pulleys are located.
3. Remove the Return Mechanism Cover: Locate the return mechanism cover, typically a black plastic cover at the front end of the frame. Slide this cover out. Be cautious, as there might be some residual tension from the shock cord.
4. Release Tension and Disconnect: With one hand, hold the existing shock cord to maintain control. Use your other hand to disconnect the cord from the pulley. Pay close attention to how the cord is connected and routed, as you will need to reassemble it in the same manner. Slowly and carefully release any remaining tension on the old shock cord.
5. Remove the End Cap: Loosen the bolt on the end cap just enough to unhook the cord from the frame. You don’t need to completely remove the bolt. Depending on your model, you may need a 5/32 inch hex wrench and a 7/16 inch combination wrench for this step.
6. Remove from Traveling Pulley: Detach any “scam pieces” or plastic sleeves from the old shock cord. Then, carefully remove the shock cord from the traveling pulley assembly. The old cord should now be completely free and can be discarded.

1. Install Through Traveling Pulley: Take your new Concept2 shock cord. Find the midpoint of the cord and feed it through the traveling pulley. Ensure both ends of the cord are equal in length before proceeding.
2. Route Through Frame: Guide the new shock cord through the frame, following the exact path of the old cord. It’s crucial that each side of the cord goes straight back and is not wrapped around the chain or twisted. Reference any diagrams or notes you took during disassembly to ensure correct routing around the various pulleys at both the bottom and top of the frame.
3. Connect to Pulley Axle: Attach the “scam pieces” or plastic sleeves back onto the ends of the new shock cord. Connect these pieces to the pulley axle, mirroring how the old cord was attached. Double-check that the cord paths are untwisted and clear of any obstructions.

Reassembly and Final Checks

1. Reinstall End Cap: Secure the end cap back onto the frame, ensuring it hooks onto the top pulley axle. Tighten the bolt using your T27 6-lobe driver or appropriate wrench.
2. Reinstall Return Mechanism Cover: Slide the black plastic dust cover back into its slot at the end of the rower. Make sure it’s fully seated and aligned.
3. Rejoin Rower Sections: Carefully upright the flywheel frame and reconnect it to the monorail section of the rower. Ensure the connection is secure.
4. Test and Adjust: Give the handle a few pulls to test the new bungee cord. The handle should retract smoothly and with consistent tension. If the chain still recoils slowly or inconsistently, re-inspect the shock cord’s path for any twists or incorrect routing. You may also need to adjust the shock cord tension if your specific model allows for it, though a new cord usually provides adequate tension.

Maintaining Your Rower for Longevity

Replacing the bungee cord is an important step, but consistent maintenance ensures your Concept2 Rower remains a reliable fitness partner for years to come. Regular inspections and preventative measures can significantly extend the life of your machine and its components.

Periodically, inspect all cords on your rower for any signs of wear, fraying, or damage. Concept2 recommends inspecting these every 500,000 meters of use, or approximately every 50 hours. Beyond visual checks, you should also untwist the cords if you notice them becoming tangled or causing a “lumpy” feeling when you pull on the handles. This twisting can lead to premature wear. To untwist, pull both handles out as far as they go, hold the cords at the top bracket, and allow the handles to spin freely. Run your hand down the length of each cord to encourage untwisting.

Beyond the bungee cord, ensure other vital components receive attention. Regularly clean and oil the chain (every 50 hours of use is a good guideline), wipe down the monorail after each workout, and periodically clean the flywheel to prevent dust accumulation that can reduce drag factor. These simple yet effective practices contribute to a smoother, more durable, and ultimately more enjoyable rowing experience.

Buying Guide: Choosing the Right Concept2 Bungee Cord

When replacing your Concept2 Rower’s bungee cord, the key is to ensure you get the correct, genuine part. Concept2’s “shock cord” is a specific component designed for their rowers, primarily Model C, D, and E Indoor Rowers.

The most important factor is model compatibility. Always verify that the replacement shock cord you purchase is specifically intended for your Concept2 Rower model. While Model C, D, and E often use the same general replacement part, it’s always best to check the product description or consult Concept2’s support page. Using an official Concept2 replacement part guarantees optimal fit, the correct length (typically 380cm or 12′ 6″), and the appropriate elastic properties to provide the consistent handle recoil your rower needs.
