Made for Surly with high-quality, well-sealed Enduro cartridge bearings - this is the replacement BB you want for your Offset Double crank. Also compatible with other 24mm spindle cranksets, such as Shimano Hollowtech II or others. NOT compatible with stepped-spindle cranks, such as SRAM.
The Enduro bearings feature double labyrinth seals, meaning they actively shed and stay clean of dust, muck, and grime, even in wet and muddy climates.
