Wheels MFG BB Conv BB BB30 To Outboard Shi Black

Wheels Manufacturing BB30 to Outboard Bottom Bracket lets you run 24 mm spindle cranks (Shimano Hollowtech II, many FSA/Race Face 24 mm, etc.) in BB30 or Specialized Alloy OSBB frames without loose adapters. Two machined aluminum cups thread together across the 42 mm ID shell (68–73 mm wide), moving the Enduro bearings outboard for better alignment, creak reduction, longer bearing life, and easier service. Uses a 44 mm 16‑notch tool for installation; includes silicone dust shields. Note FSA MegaExo spindles measuring 24.07 mm may require different bearings.
