Ive been wearing out my DA cassette's and decided to make a change but heard there were sometimes problems making the SRAM silent, this is how I did it.
Installed new hollow pin SRAM PC-1090 Chain
' Install Powerdome Cassette without Freehub spacer
' Tighten to 15nm (all that is needed)
Go ride the bike, in my case the problem was noise in the 22/23/25 cogs
In the inner chain ring, Outer chain ring was fine
' Shift to smallest chain ring and smallest cog and tighten barrel adjuster 1 click clockwise (smallest chain ring and cog because the cable is at its slackest setting and you want to get the full adjustment)
' Go ride and repeat clockwise adjustment until silent, in my case 3 clicks clockwise.

ps: the PD cassette is very sensitive to derailleur adjustments, if yours is out re-adjust the H/L limit screws (as per Park Manual)with the DA cassette only, I found it impossible to do it with the SRAM cassette.

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.

This cassette seams to be much more fluid, and it seems to transfer the power better since it is made out of one piece of steel for the first 7 cogs.

Went on a club ride yesterday and was able to ride with the fast guys for 40 miles doing between 22-27 MPH and most of the way at 24 MPH. On the same course 3-weeks earlier I struggled to keep with a group doing 19-21 MPH. Is it really the cassette that made the diffence? I don't know for sure but so far I'm quite pleased with my efforts.
