Introduced in 2016, these lightweight, FEA-optimized, solid forged crankarms bring Cannondale System Integrated performance to more pricepoints than ever before. Lighter than Ultegra or Force Carbon cranks, they share more than just a family resemblance with the HollowGram cranks. They share the same interchangeable spider interface and are fully BB30 and BB30A compatible. The Cannondale Si crankset represents a fantastic upgrade for any BB30 equipped bike.
this is interesting. Do I need a special tool to switch out the spider? my first bike I havent put together myself so the inner workings remain kind of a mystery (hydraulics, press in bbs)
