Bicycle Bottom Brackets Adapte
Bridge shell sizing gaps and run your choice of crankset with our Bicycle Bottom Brackets Adapter collection. Designed to solve common interface mismatch issues, our adapter solutions allow you to install 24mm (Shimano), 28.99mm (SRAM DUB), or 30mm spindles into oversized frame shells like BB30, PressFit 30, and PF92 without changing your entire bottom bracket assembly. Manufactured from high-precision CNC-machined 6061 aluminum and durable low-friction polymers, these press-in sleeves, reducer spacers, and threaded conversion cups prevent side-to-side play and seal out road grime and water spray. Whether you are converting a PressFit frame to take a traditional threaded BSA bottom bracket or adapting a 30mm shell down to a 24mm spindle, our adapters provide a creak-free, aligned foundation for optimal power transfer.
