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.
Huh I’ve never heard of that! I didn’t even know what I was missing.
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.
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 “32 x 10-50” and “34 x 10-52”:
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 “tighter cassette”? The biggest differences are actually between the highest gears (10, 12, 14, 16, 18, 21) and there’s 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 I’m “between gears” is that 42 and 50. Unfortunately moving to a 34 x 10-52 doesn’t solve that problem.
Starting to think about this a little bit for gravel too. I’m running a mullet set up on my Checkpoint with 40t upfront and 10-50T in the rear. It’s been fine for all the climbs but there have been some times I’ve 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.
Broke a chain today (twice), so of course I had to order a new chain, front chainring 34t (up from a 32t) and the new 520% Eagle cassette!
It’s compatible with AXS, which I have. The new frame will come when the Spark RC 900 gets a new design, likely for 2022.
