Problem Solvers BB30 / PressFit 30 Bottom Bracket Adaptor

The Problem Solvers BB30/PressFit 30 adapters enable the usage of external bottom bracket crankarms (24mm spindles) with BB30 and PressFit 30 bottom bracket bearings. These adapters fill the gap between the 30mm ID of the bearings and the 24mm OD of the spindle, with included spacers to fine-tune chainline and bearing load. The kit comes with crankset-specific spacers for Shimano Hollowtech II, Race Face X-Type, and FSA MegaExo, and it is compatible with road and mountain (68/73mm) bottom bracket shells. The GXP Spacer Kit is sold separately.
