The Sram XG-1080 cassette offers an innovative approach to 10-speed cassette design. Made from heat-treated steel, the cassette employs a skeletonized dome-like construction, delivering a maximum stiffness to weight ratio.
Weaknesses: Put a new drive train on last spring. Only two chains neither worn past .75 on the park tool and the cassette is already worn out on the 3rd chain.
I dont think I will be purchasing anymore sram cassettes. I had trouble with their 9speed and now the 1080 has worn out. Its the bigggest cog in the back is made of aluminum to save some grams. I put a new chain on and it skipped under medium pressure. Im going back to shimano xtr never had this issue with shimano.
