| SRAM Red OG-1090 PowerDome Cassette by Microdyne Precise | I had to replace a cassette that originally was the Rival cassette, also made by SRAM. This cassette, although much more expensive than a Dura-Ace cassette, I was afraid to change brands since the rest of the groupo is SRAM. In any event, the replacement is a great investment. The higer gears (1-7) are milled out of one piece of alloy while the three lower gears (8,9,10) are attached by a small cage. The cassette will fit all 10speed Shimano/SRAM systems, although I have had problems with a SRAM 8 speed cassette not shifting well on a Shimano system equipped mountain bike, I can't be sure that mixing brands is a good idea.
Overall, this is a precise shifting cassette. I do wonder though if SRAM's design is a durable as Shimano's or Campy's. I had to change out the Rival cassette with less than 3000 on the drive train. | | SRAM Red OG-1090 PowerDome Cassette by Microdyne Product Description | | Machined from a single-forged steel form, heat treated and then shaped in a complex series of CNC-guided operations for extra stiffness, durability and simplicity. 35pct harder than titanium and 15pct more rigid than any other cassette on the market. OpenGlide technology removes specific amounts of material from the smaller cogs, to allow for smoother shifting action between gears, even when your bike is under stress. Shimano/SRAM 10-speed compatible (not compatible with Shimano Dura-Ace WH-7801). |
