really? a full pound? I did a quick google and got the following complete groupset weights (w/o brakes)
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
Xx1 11 chain - 252g
Total - 853
Xx1 12 derailer - 265g
Xx1 12 shifter - 123g
Xx1 12 cassette - 362g
Xx1 12 chain - 249g
Total - 999
So yeah, itās not a lb, but itās almost a half which is a big jump for something thatās 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 itās also a sprung mass so it would have an effect on how well the suspension worked. I guess in the end itās 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.
Iād 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 didnāt realize shimano never released the one they talked about
Yeah Iām strongly considering Shimano for my next bike because of the 10-45. I just donāt need a 10-50 living in Michigan.
Iām almost certain they did. A quick google shows it for sale and in stock on a couple websites.
Thatās good to hear. I was just going off what Steve said above. Maybe Iāll look into that system
Iām 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. Itās not listed on Shimanoās website currently.
Huh Iāve never heard of that! I didnāt even know what I was missing.
From what Iām aware, it was never produced. Too bad. An XTR-Di2 setup with that would have been pretty sweet.
At this point Iām happy with my 11 speed setup, so sans playing with cassette options for that Iāll 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 wonāt 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.
Iāve been pretty happy with e*thirteenās 11sp 9-46T, though I know that isnāt 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 havenāt had an issue yet, though I donāt really ride in wet conditions much living in CO and Iām a lighter rider. The 12sp 9-46T of theirs seems to get positive reviews from everyone Iāve 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 itād 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, Iād 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.
So this is interesting if you buy the new 10-52 but also move up to a 34t chainring (from a 32t). Essentially your bailout gear remains the same but all of your other gears get a slight increase. I think the solution, for me at least, will be to have the 10-52 and swap out between the 34t (XC racing) and 32t (MTB 100s).
Below chart shows the differance between ā32 x 10-50ā and ā34 x 10-52ā:
I felt the same way, but looking at the gear ratio, where would you supplement in the gears in place of the 50/52t cog for that ātighter cassetteā? The biggest differences are actually between the highest gears (10, 12, 14, 16, 18, 21) and thereās not much room in there for any remarkable difference. If I think back to all my riding/racing (outside of MTB 100s), it seems like the only time Iām ābetween gearsā is that 42 and 50. Unfortunately moving to a 34 x 10-52 doesnāt solve that problem.
Starting to think about this a little bit for gravel too. Iām running a mullet set up on my Checkpoint with 40t upfront and 10-50T in the rear. Itās been fine for all the climbs but there have been some times Iāve been spinning out on the high end. Being able to put on a 42t up front and then the 10-52T in the rear would help without giving up anything for the big climbs.
