In addition to the poor shifting of my recon alloy cassette, it now skips suddenly under heavy accelerations; not exactly confidence inspiring. So I need a replacement that preferably lasts longer than 2000 miles. New sram red looks nice, lighter than DA even though it's made of steel/alloy as opposed to ti/steel. Can anybody comment of the durability of this cassette? Is it still loud as balls? Anybody weigh an 11-26 new sram?

i have both cassettes but in 11-28 and i can tell you that i do not think the xg is loud. I put both of them on the scale and there is about a 24-27 gram difference between the two, i can remember but it is in the 20's. i have the xg with the new reds and it is 154grams and the DA with the DA. i think DA is a smoother action going from cog to cog. I cant tell you what one last longer as i have only been able to put 800miles on both but there is some tooth scaring in the 28 tooth cog of the xg.

I have the XG1090 in 11-23 and 11-28. They weighed 133g and 160g respectively. I find them to be extremely quiet. I basically have no drivetrain noise now.

I don't have enough miles on either to assess durability but for what it's worth I have put over 5000 miles on some older Red cassettes and they still shift well. I can only imagine it would be the same case for the new ones. The largest cog is aluminum for the new cassettes but I rarely use that cog.

I recently purchased the xg1090 in 11-26. It weighs 149g with lock ring on my scale. The og1090 in 11-26 it replaced weighs 166g on the same scale. I haven't used it yet so I can't comment on your other questions on longevity or noise.

My tuned OG1090 11-28 is pretty damn quiet, light, and affordable.
Way more affordable than the 7900 cassette, a fraction of the XG1090, durable, quiet, unique.
Just a hint.

You'll find the graphic in the thread in one of my posts. If you'd like the original PDF version, I can send that to you by e-mail (send pm).
Acetone will take off the backplate, use a strong aluminum/steel bonding glue to put it back on.

i have both cassettes the xg 1090 is quieter then the dura ace but if you keep it the same brand of your group

Bit the bullet and bought an open box xg-1090 11-26 cassette from treefortbikes in Michigan. It weighs in at 148g with the lockring.

Xg1090 is the quietest cassette i've experienced, specially when matching with the 1091r chain.
11/28 weights just 158g with lockring.

I got plenty of miles on my last OG -1090 11-26 cassette. I was actually quite impressed with how long it lasted - about 15,000 miles. I never weighed it though.

I did find that it tended to work better with Sram chains.
