SRAM RED Cassette OG-1090
Lighter than the “other two”, harder than titanium, and featuring an advanced monocoque milled-steel design, the SRAM Red OG-1090 Cassette is just plain awesome. The top eight cogs of the OG-1090 are actually machined in one piece from a solid block of cromoly steel, then nickel plated for hardness. That means that they, or it, is or are amazingly stiff, bare-knuckle tough, and light enough to justify the cost before you even consider the simplicity of not dealing with eight cogs and spacers. Two floating final cogs complete the OG-1090's ten speeds, with the same smooth-shifting OpenGlide tooth configuration as the top eight.
Bottom Line: We hate to call anything the “best”…but the OG-1090 Cassette makes a strong case.
Change me.
