ZRACE ITA-DUB Bottom Bracket Italian Threaded 68/70mm DUB Road MTB

ZRACE ITA-DUB Bottom Bracket Design and Compatibility Features

Italian threaded 68/70mm shells remain common on vintage road frames and some gravel platforms, yet modern DUB cranksets dominate performance upgrades—this bracket solves that pairing without compromise. Smooth sealed bearings eliminate play and resist contamination from wet conditions, preserving reliable power transfer across thousands of pedal strokes. The integrated cup geometry centers your crankset precisely, critical for electronic shifting systems and power meter accuracy on both road and MTB drivetrains. CNC-finished surfaces reduce drag and create perfect mounting surfaces that prevent creep under load. This solution lets you preserve a beloved frame while equipping it with contemporary performance technology.
