Notes from MyBikeThing
The Campagnolo Chorus bottom bracket exemplifies Italian engineering at its finest. This cornerstone component showcases Campagnolo’s mastery of precision bearing design and weather-sealed construction. The legendary smoothness of Campagnolo’s bottom bracket bearings isn’t just marketing – it’s the result of exacting manufacturing tolerances and premium sealed cartridge bearings that have earned their reputation over decades of use.
What sets this apart is Campagnolo’s exceptional sealing system and perfect chainline engineering. The precisely machined cups and meticulously engineered bearing preload deliver that signature silky-smooth Campagnolo feel that only gets better with miles.
Condition
Fresh from our workshop inspection, this bottom bracket presents in mint, like-new condition. The threads are pristine, the spindle’s surface finish is perfect, and the bearing seals are intact and supple. Both cup faces show zero installation marks.
Every component we sell goes through our comprehensive testing protocol before being offered to fellow cyclists. As always, backed by MyBikeThing’s 30-day return policy because we stand behind what we sell.
Workshop Wisdom
The perfect bearing preload from the factory means no adjustment is needed, while the robust sealing system ensures years of smooth operation. Worth noting is the precise spindle length – 111mm provides ideal chainline for most road double or triple Campy 9- 10 speed groups.
