Developed to seamlessly interface an asymmetric T47a frame shell (77.5 mm width) with oversized 30 mm spindle cranksets, this premium component eliminates the structural alignment variances, mechanical play, and creaking associated with multi-part adaptor systems. Built with the explicit manufacturing goal of outlasting the bicycle frame itself, the BB ALPHA structural design optimizes precise bearing race alignment across the spindle, delivering flawless wattage transfer and maximizing your overall drivetrain stiffness-to-weight ratio.
