Is this compatible with Shimano derailleurs?

The 6901 bearing (12x24x6mm) is compatible with many Shimano rear derailleur jockey cage applications. Verify the jockey wheel bore and housing dimensions match before ordering — Shimano jockey wheel specs vary by model generation.

Should I replace the top and bottom jockey wheel bearings together?

Yes — always replace as a pair. Mixing a new and worn bearing in the same jockey cage causes uneven wear and inconsistent cage alignment.

What is ABEC-5 vs standard jockey wheel bearings?

ABEC-5 has tighter dimensional tolerances than standard ABEC-3 — the races are rounder and smoother. For jockey wheels, this means lower rolling resistance and more precise chain tracking under load.
