EDCO competition bottom bracket with eccentrics

Repairing a bike frame with an EDCO eccentric cupset bottom bracket

When a bike frame has an alignment issue or an ovalized bottom bracket shell, the EDCO competition bottom bracket with eccentric cups proves to be an ideal solution. This drivetrain component compensates for frame imperfections while optimizing pedaling efficiency and power transmission.

What is an eccentric cupset bottom bracket ?

An eccentric bottom bracket is designed to adjust the position of the crank axle to compensate for misalignment or to fine-tune belt tension when no tensioner is available. It typically consists of eccentric cups that allow slight modifications to the axle position without altering the frame.

The EDCO competition eccentric bottom bracket is highly regarded for its precision and durability. Made from machined aluminum, it ensures excellent longevity and optimal rigidity for efficient power transfer.

Features of the EDCO competition bottom bracket

• Compatibility: Suitable for frames requiring bottom bracket alignment correction.
• Materials: High-precision aluminum for enhanced durability and reduced weight.
• Crank Axle Compatibility: Supports various axle standards depending on the model (BSA, ITA, BB30 with adapters).
• Adjustment System: Eccentric cups offering fine-tuned alignment control.
• Application: Ideal for repairing damaged frames or optimizing belt-driven transmission tension.

Why choose an eccentric cupset bottom bracket for frame repair ?

A damaged bike frame or a poorly machined bottom bracket shell can compromise pedaling smoothness and cause premature drivetrain wear. With an eccentric bottom bracket, it is possible to correct these defects and improve:

• Chainline alignment, preventing unnecessary friction and optimizing efficiency.
• Crankset stiffness, ensuring effective power transfer while pedaling.
• Versatility, allowing compatibility with different axle types and crankarms based on rider preferences.

Installation and adjustments

Installing an EDCO eccentric bottom bracket requires precision. Here are the key steps:

1. Remove the existing bottom bracket: clean the bottom bracket shell thoroughly to remove debris.
2. Install the eccentric cups: ensure proper threading alignment and apply a specific grease.
3. Adjust the eccentricity: set the axle position according to the required tension or alignment correction.
4. Secure and tighten: confirm that the assembly is properly fitted without excessive play.
5. Test the pedaling motion: verify that the drivetrain runs smoothly without resistance.

Conclusion

The EDCO competition bottom bracket with eccentric cups is a major asset for repairing a misaligned bike frame or adapting a crankset to a specific drivetrain setup. Thanks to its precise and robust design, it enhances bike longevity, pedaling comfort, and overall efficiency. A wise choice for cycling enthusiasts looking to maximize performance and durability !
