Description of Cannondale SISL2 Hollowgram Spider Rings compact Road Crankset
System integration in perfection!
Defining the global standard in ultra-light, super stiff cranksets.
The crankarms are constructed from a 2000-series aluminum that has nearly double of the fatigue life of other aluminium alloy. Crankarms are connected to thin-walled, and hollow pieces thanks to the "two-piece"-technology. In combination with an oversized 30 mm aluminum bottom bracket axle it guarantees superior balance of strength, weight and stiffness. The crankarms are CNC-machined for optimum strength and light weight.
The extremely lightweight black OPI chainring spider was made in 3D forging process and brought to completion by CNC milling. Besides the incredibly beautiful look the unusual design offers also excellent rigidity values.
There’s a formula Cannondale use to help their sponsored riders win races and take championship titles: System Integration. Cannondale shaves weight, improves stiffness, and use fewer moving parts than other competitors.
Complete crankset includes spindle and all bottom bracket parts for PF30, BB30, and original in-frame BB30 system.
Note: Cannondale SISL2 Hollowgram cranks are delivered with long axle. For mounting spacers are required. As an alternative QC612/ Si Spindle 104mm Road can be mounted.
