The new Cannondale FSI has redesigned its chainstays, shifting the rear hub 6mm to the right in order to keep chainstays as short as possible. To maintain straight chainline we have created a specific spider for this frame, which moves the chainrings out by 7mm. Our axle is 131mm long, 7mm less than the original FSI axle. This way we can mantain a straight chainline and a narrower Q-factor. Compatible ONLY with NEW FSI frames, with Capo and Hollowgram cranks, and XX1 chainring. Includes axle, spacers and spider.
