Product Information

Full details

The Hope Spiderless Retainer Ring (RR34EBRSPN) is an essential performance upgrade for e-bike owners seeking a reliable, lightweight, and streamlined drivetrain. Designed specifically for Bosch, Brose, and Shimano motor systems, it uses a narrow/wide tooth profile to securely grip the chain, effectively preventing dismounts during aggressive trail riding. While it offers a quiet and efficient pedaling experience, users should verify their specific motor interface before purchase to ensure proper compatibility.

FAQs

Does this chainring work with all e-bike motors?

No, it is designed specifically for Bosch, Brose, and Shimano systems. Please verify your motor brand compatibility.

Can I use this with a 12-speed chain?

Yes, this ring is engineered to be compatible with 9, 10, 11, and 12-speed drivetrain setups.

Do I still need a chain guide after installing this?

The narrow/wide design is intended to provide enough retention to ditch the chain guide for most riding styles.

Is the material durable enough for aggressive riding?

Yes, it is constructed from high-grade 7075-T6 aluminium and features a hard anodised finish for maximum durability.

How do I know which motor interface I have?

Consult your e-bike manufacturer's specifications or inspect the motor housing, which is typically branded with the manufacturer's name.

Does the spiderless design save weight?

Yes, by eliminating the separate spider assembly, the total drivetrain weight is reduced.

Troubleshooting

Excessive chain noise during pedaling

Check that the chain is correctly seated in the narrow/wide pattern and ensure the chain is properly lubricated.

Chain dropping on rough terrain

Inspect the teeth for wear. If the ring is still in good condition, check the chain length and ensure your rear derailleur clutch is engaged.

Difficulty installing the ring

Verify you are using the correct lockring tool for your specific motor brand and ensure the mounting interface is free of grime.

Pros and Cons

Pros

  • Eliminates the need for cumbersome chain guides
  • High-strength, lightweight 7075-T6 aluminium build
  • Extremely durable hard anodised finish
  • Compatible with a wide range of speed setups
  • Quiet operation with reduced drivetrain drag

Cons

  • Specific to e-bike motor interfaces (Bosch, Brose, Shimano)
  • Not compatible with standard non-electric cranksets
  • Requires specific tools for direct mount installation

Setup, Compatibility & Care

Installation requires removing your existing chainring or spider assembly using the appropriate motor-specific lockring tool. Ensure the mounting surface of the motor is clean and free of debris before seating the ring.

Compatibility Checklist:

  • Motors: Compatible with specific Bosch, Brose, and Shimano e-bike motor systems.
  • Speeds: Designed for 9, 10, 11, and 12-speed chains.

Care Instructions:

To maintain the longevity of the hard anodised surface, avoid using harsh caustic cleaning agents. Regularly inspect the teeth for wear after muddy rides and ensure your chain is properly lubricated to minimize friction and premature degradation of the narrow/wide profile.
