AbsoluteBLACK Road Oval Cannondale Spidering 2x Chainrings
Description
absoluteBLACK are pleased to announce a new addition to their portfolio of oval chainrings. The idea was born from owners of Cannondale Hollowgram cranks wanting to ride our Ovals. Previously the only option was to go back to the “old school” spider + chainring combo which is not only heavier but less appealing. Therefore, a direct mount solution that is not only super light but also has excellent shifting capabilities came into creation.absoluteBLACK have taken slightly different route to create this direct mount 2x ring set. The decision was made to use 5 small titanium bolts to connect the two rings together making it “one-piece”. Cnc'ing everything from one piece has a lot of limitations in the design concept and machining process. Making two separate chainrings leads to the usage of much thinner plates maximizing the strength and stiffness. Taking this different approach allows the final product to be stiffer, use AB’s proprietary shifting ramps like the other AB premium chainrings and profile the teeth in the way that is best for performance.Oval chainrings are taking the market by storm and there is a reason for it - they just work. absoluteBLACK have been working for years in perfecting the geometry and conducting tests to prove that this technology really makes the difference. Having their own laboratory, scientists and co-operation with leading Universities in the world really helps them to push the envelope in this field. Having access to pro tour teams, like the UAE Team Emirates places absoluteBLACK at the forefront in providing scientific biomechanical optimization for all team riders. This gives absoluteBLACK a full spectrum of pedalling motion data, from pro tour stars to an average cyclist to help in the development of world leading products that maximizes rider’s performance.Available in 50/34T and 52/36T combinations with sub-compact sizes coming soonKey Features:Size (Weight): 50/34 178g, 52/36 TBC,Compatibility: Cannondale Hollowgram Si, SiSL, SiSL2. chain: 10, 11spd,Materials: cnc machined 7075 Txxx Aluminum.
