NEW SRAM XO, XX and XX SL transmissions drop - derailleur gone, b-tension gone, limit adjust - gone

Your cassette lasts 12 years? Do you have several bikes that you rotate or do you just never ride? I ride about 30-40 times a year and I have to replace my Shimano cassette at least every two years.

 

For the last 12 years, until last year, I had a 2 bike rotation and rode an average of 2-3 times a week. One geared bike, the Anthem, and the other a SS. Most of the rides were mellow and not “race training” efforts. Drivetrain on the geared bike is XT. Maybe it’s how I ride, the maintenance, where I ride, or the combination of all these that makes the parts last longer. I don’t really know. They just do.

 

@DangerDirtyD rides tires older than your drive trains.

If I get a year out of a cassette, it's a win...

 

Now that I live in the mountains and not the cement jungle, I know my parts won’t be lasting long.
I do change my tires every year, if not sooner. There’s that.

 

I have 6,104 miles on my XX1 cassette.

 

years of design, FEM, litening holes and it looks like the derailed I have had on my bikes since 1960. I thought there would be a quantum leap in technology. Giant cassette rings but the top end is limited by the tiny chain ring and the 10 on the back

 

4000 on both of my X01 cassettes. One is on my backup wheelset.
