    “The Holy Grail of MTB Cassettes”

    The Good: ~Spools-up extremely fast ~Sub 210g weight is consistent ~Incredible wear, from machined, inner 8 cogs ~Smooth, instant telepathic shifts, rivals Shimano XTR ~Materials science at its finest ~High resale value

    The Bad: ~Pricey ~SRAM lied about replaceable 36t cogs, in their ad campaigns

    Overall Review:

    Upgrading from my hefty, 355g SRAM PG-1070 cassette - the 207g XG-1099 spins up so fast, it's almost like losing four additional teeth on your granny chainring. The 148g difference CAN BE FELT...the moment you spin the cranks. Climbs that normally petered me out can finally be cleared, due to the reduction of rotating axial weight.

    If you are strong enough to stay away from using the alloy 36t cog - you can also expect 3-4 seasons of hard trail riding, on this cassette. Just be sure to religiously monitor your chain wear and this cassette will easily outlast many lower-end cogs by 3:1...making this component a decent value(somewhat).

    Currently, the only aftermarket maker of replacement 36t cassette cogs is Experimental Prototype, in Sweden. SRAM decided it unprofitable to offer replacement cogs, after all the hype about making them available. They simply lied...

    Miscellaneous SRAM XX CassetteThe revolutionary machined design of the XX Cassette uses the same grueling manufacturing techniques that produced the PowerDome road cassette. With X-Dome, eight of the cogs are CNC-machined together out of a single block of billet steel, creating an incredibly lightweight, precise, and strong cassette. Its a process that takes nine hours per cassette! The aluminum large cog can be replaced as needed. You have never seen a cassette that looks like this. The open design aids in mud clearance, giving you cleaner shifting performance and longer component life. 10 Speed X-Glide shifting X-Dome design CNC 4130 chromo w/ 7075 T6 large cog Published weight 208g (11 - 36), 185g (11 - 32) Optimized for use with SRAM PC1090, PC1090R chain
