I don’t see the point this is a 5% difference? You’ve got a 20% jump between 11 and 12? It’s a $275 cassette? I’d just adjust the front ring.
11 speed 10-42 is a full lb lighter than xx1 or xtr 12.
Don’t skip leg day.
I’m hoping someday one of them makes a high end 10 speed 10-42. We know it’s possible seeing as shimanos deore 10 speed 11-42 works great and is very popular.
really? a full pound? I did a quick google and got the following complete groupset weights (w/o brakes)
- XX1 11 speed = 1430g (From BikeRumor.com)
- XTR 11 speed = 1526g (From Bikeradar)
- XX1 12 speed = 1502g (From BikeRumor.com)
- XTR 12 speed = 1600g (From Pinkbike)
So worst case scenario you gain 170g (0.375lb) by going from high end 11 speed to a high end 12 speed drivetrain.

I really wish that Shimano had produced the 10-45t cassette that they originally announced. I want one of those with the AXS setup.

Xx1 11 derailer - 220g
Xx1 11 shifter - 121g
Xx1 11 cassette - 260g

Total - 853
Xx1 12 derailer - 265g

Xx1 12 cassette - 362g
Xx1 12 chain - 249g
Total - 999
So yeah, it’s not a lb, but it’s almost a half which is a big jump for something that’s supposed to be an upgrade , especially when you consider most of it is in the cassette which is one of the worst areas to carry uneeded weight.
Agree. 10-44/45/46 would be much better for xc

True, though at least its close to the axle so its inertia is much less than if that weight difference was in the rim or tire. And it’s also a sprung mass so it would have an effect on how well the suspension worked. I guess in the end it’s a question of whether the smaller jumps between gears or the increased range is a larger performance benefit than the increased weight. Which I think most people would take those benefits over the weight any day.
I’d upgrade to 12 if Sram did a 10-44/45/46 in xx1 just for the tighter gear jumps, but the 50/51/52s are unnecessary to me in my area.
I didn’t realize shimano never released the one they talked about
Yeah I’m strongly considering Shimano for my next bike because of the 10-45. I just don’t need a 10-50 living in Michigan.
I’m almost certain they did. A quick google shows it for sale and in stock on a couple websites.
That’s good to hear. I was just going off what Steve said above. Maybe I’ll look into that system

I’m also considering trying the e13 9-42 11 speed cassette.
467% range and you can just run a smaller chainring.
Sorry I should have clarified that I was referring to the 10-45T 11-speed cassette. It’s not listed on Shimano’s website currently.

Huh I’ve never heard of that! I didn’t even know what I was missing.
From what I’m aware, it was never produced. Too bad. An XTR-Di2 setup with that would have been pretty sweet.
At this point I’m happy with my 11 speed setup, so sans playing with cassette options for that I’ll probably either wait for 10-45 axs or xtr di2 12 to upgrade.
I wonder just how different the derailleur is. Personally I do seldom use my 50t that I have no desire for a 52, but if I could get some crisper shifting that would be welcome

Has anyone tried using a shimano cassette on Sram 12 or Sram cassette on xtr mechs yet? I know shimano and Sram say it won’t work but they said the same thing about 11 speed and those worked great mix matched
For the majority of my riding the jump for 10-50 to 10-52 would not be of any benefit. However I would have made use of it at Leadville from Mile 80 to the finish. I ran a 32t up front and having 52t in the rear would have been helpful up Powerline and also for that last steep rocky section near the finish. I was thinking I might run a 30t up front next time, but the 10-52t seems like the ideal fix.
I’ve been pretty happy with e*thirteen’s 11sp 9-46T, though I know that isn’t the case for everyone, so you may have already ruled it out. I know people have had some premature wear on the aluminum cogs, but I personally haven’t had an issue yet, though I don’t really ride in wet conditions much living in CO and I’m a lighter rider. The 12sp 9-46T of theirs seems to get positive reviews from everyone I’ve talked to though. Just throwing that out there.
If SRAM came out with a 10-46T 12sp cassette, I might actually consider upgrading to Eagle but until that happens, my 11sp with the 9-46 is working great and is lighter anyhow. I may eventually upgrade and throw the e*thirteen 12sp on there, but it’d be nice if SRAM offered their own option like that.
My thoughts exactly. A few spots on top of columbine as well. I use the 50 as a bail out gear, so the lower the better. Smallest ring I can run on the front is a 32 with my powermeter, I’d run a 30 if I could.
For less extreme and shorter events, I do wish sram would offer a tighter 12 sp cassette that maxed out at 40 or 42.
