Rear Derailleur Jockey Wheel Compatibility Checklist for B2B Buyers

Rear derailleur jockey wheel sourcing depends on compatibility information rather than appearance alone. This checklist helps bicycle brands, importers, distributors, wholesalers and assembly projects organize the key inputs before requesting a quotation.

Quick Answer for Buyers

Prepare the tooth count, available dimensions, center interface or bore information, cage spacing, derailleur or drivetrain reference, bearing or bushing structure if already specified, finish, packaging, expected quantity and destination. Add a sample, drawing or clear reference photos when available.

Current QUNKE Compatibility Reference

QUNKE currently lists oversized pulley cage systems for selected Shimano 11-speed rear derailleur families. Confirmed examples include UT models for R8000/R8050/R9100/R9150 families, 105 models for R7000, 5800-family models, and 6800-family models covering 6800/6870/9000/9070 references.

The confirmed pulley combinations are 13T / 18T for UT and 105 versions, and 16T / 17T for 5800 and 6800 versions. Construction uses a carbon-fiber cage, aluminum pulleys and ceramic bearings. Shimano 5700 is a 10-speed family and should not be treated as an 11-speed compatibility reference.

These examples are sourcing references only. Final compatibility should be reviewed against the exact rear derailleur family, dimensions and buyer-provided reference information.

1. Identify the Target Drivetrain Application

Review the current Rear Derailleur Jockey Wheels page before preparing the inquiry.

2. Confirm Tooth Count

State the required tooth count and the application it is intended for. Tooth count should be reviewed together with the drivetrain reference and other compatibility dimensions.

3. Prepare Dimensions and Interface Information

A visual match alone should not be treated as proof of compatibility.

4. State Bearing or Bushing Requirements

If a bearing or bushing structure is already specified, include it in the RFQ. If it is not confirmed, ask for project review instead of assuming one structure will fit every derailleur system.

5. Include Finish, Marking and Packaging

Custom development and private-label discussions can be prepared through OEM / ODM.

6. Define Inspection Points

Buyer-defined inspection points can include key dimensions, cage fit, rotation, appearance, finish and packaging checks according to the confirmed project. See Quality Control.

7. Include Purchasing Information

For buyers validating fit before a larger order, review the Sample & Trial Order process.

Frequently Asked Questions

Can compatibility be confirmed from a photo alone?

A photo can support an initial discussion, but dimensions, cage information, interface details and the drivetrain reference provide stronger evidence for compatibility review.

Can I send a physical sample?

Yes. A sample, drawing or clear reference photos can support the project review.

Can custom color, marking or packaging be included?

Yes. Include the required finish, marking, labeling and packaging information in the RFQ.
