An adapter for BMX bottom brackets with a 51 mm diameter is now available, allowing cyclists to use a bottom bracket with a BSA or square taper cartridge system on their BMX bikes. This adapter is manufactured with high precision, ensuring that the bike’s chainline remains unchanged, even compared with installing a BSA or square taper bottom bracket directly on the bike.
The ADTBB-51 model adapter also features auto-aligning technology. Developed in-house, this technology speeds up the adapter installation process on BMX bikes by providing better tolerance when installing the bolts.
