Description
Notes from MyBikeThing This Shimano Ultegra BB6600 bottom bracket is the sweet spot between premium performance and sensible pricing – the kind of component that delivers Dura-Ace smoothness without making your wallet cry. The sealed cartridge design means you can focus on hammering out intervals instead of wrestling with loose ball bearings and grease.
Condition Description: Grey anodized finish appears intact with minimal surface wear. Threaded cups show clean threads with no cross-threading visible. Sealed cartridge unit appears complete with all directional markings clearly visible. Model number SM-FC6600 and threading specifications clearly marked on components. Bearings spin smoothly with no play or roughness
