SRAM Red Cassette
There aretimes when the simplest solution is the best one. In the case of theOG 1090 cassette, simple also means elegance, efficiency, andperformance. Traditionally a cassette is made up of many parts andSRAM re-engineered it.
The main cogset is machined out of asingle forged form that is hollow, then heat treated and then shaped ina complex series of CNC-guided operations never before seen in thistype of application. This is truly a revolutionary design that willtake you by surprise with its ingenious simplicity. The sprocketsthemselves have been designed with SRAM's proprietary OpenGlide designfor smooth as silk up and downshifts. OpenGlide features a preciselocation for a single tooth on each cog to be "open" making shiftsquick and smooth. Weight, stiffness and strength wise, the radical OG1090 cassette delivers titanium's desirable weight, with solid steel'ssuperior strength and stiffness.

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.

Love it | |

Like the one piece construction for the top 8 cogs. Very light. It makes a little more noise than the shimano cassettes but somehow it's a soothing noise, one that says "I'm about to pass you". | |

worth the cost | |

I was initially worried that having the entire cassette sit on only two connection points would end up eating my aluminum freehub, but after a season of riding there is no damage to the freehub. The weight is very low, and so far the wear is comparable to DA. Great product SRAM | |

Light and nice, pricey, limited sizing | |

This is great cassette, is super light and wears well. The price is very high and can really only be justified for weight weenies. The sizes are limited because it only comes as a 11 cog low gear. For those without compact cranks a 12 cog may be preferable. | |

Not for cross..... | |

Shifts well but don't run it for cyclocross. The mud won't clear and shifting diminishes. | |
