External BB Standard Dust Cover - Each

Phil Wood External BB Standard Dust Cover is a direct-replacement external bottom bracket dust cover designed to keep grit and moisture away from the bearing interface for smoother, longer-lasting performance. This Standard version fits common 24mm-spindle external systems and is sold each for straightforward service or replacement of a damaged or missing cover.

• Correct fit for common external BBs - Replacement dust cover for Race Face, FSA, and pre-2006 Shimano external bottom brackets
• Bearing-size specific - Sized for 24x37x8 applications to match the intended bearing/cover interface
• Helps protect bearings - Adds a barrier against contamination at the outer bearing area to reduce premature wear from trail grit and wash spray
• Service-friendly - Sold individually (each) for replacing one side without buying an entire kit
• Compatibility note - 2006+ Shimano external bottom brackets that use a #6805 bearing (25x37x7) require the Medium cover, not the Standard version
