Phil Wood External BB Medium Dust Cover is a precision-fit replacement cover for external bottom brackets that use the
#6805 bearing size. It’s the correct “medium” cover specified for
2006+ Shimano external bottom brackets with
25x37x7 bearings, helping seal the bearing area against trail grit and wash water for smoother, longer-lasting performance.
- Correct medium sizing for #6805 bearings - Required fit for 2006+ Shimano external bottom brackets using 25x37x7 bearings
- Contamination protection - Helps keep dirt and moisture away from the bearing interface to reduce premature wear
- Service-friendly replacement - Ideal for restoring sealing performance during bearing swaps or bottom bracket overhauls
- Sold individually - Replace a single damaged or missing cover without buying an entire kit
Note: This is the
medium cover for
#6805 (25x37x7) bearings; it is not the “standard” dust cover used on
Race Face, FSA, and
pre-2006 Shimano external bottom brackets with
24x37x8 bearings.
