The OG 1090 cassette’s main cogset is created out of a single forged form and in a complex series of operations that are CNC-guided, it is then heated and shaped into the finished product. Combining titanium’s weight with solid steel’s unrivaled strength and stiffness, it gives meaning to the words “highly durable”.

Lightweight: Innovative CNC‘d chromoly steel construction.
Durable: 35% harder than titanium!
Stiff: 15% stronger than its competitor.
OpenGlide technology allows for smoother transition between gears.
