The main cogset of the OG 1090 cassette is machined out of a single forged form that is heat treated and then shaped in a complex series of CNC-guided operations. Weight, stiffness, and strength-wise, the OG 1090 Cassette delivers titanium’s weight with solid steel’s superior strength and stiffness.
