as an enterprising consumer might expect, there’s one other place you can read about this new groupset :wink:

Dan, do you know if the new AXS groups can be configured to work with an 11 speed cassette? I hope so given the electronic nature of the group (no cable pull differentials to contend with).

I could be wrong but I assume I can’t replace my freehub on my Aerocoach disc (ridden on a 2012 Speed Concept 7.8) with an appropriate 12 speed freehub?

Wait, can you not get a 53x39?

“The spec and options are pretty much the same as with RED: 12 speed cassette; 10-tooth 1st position cog, and 3 chain ring size options, each with a 13-tooth differential (50x37; 48x35; 46x33).”

A friend of mine bought it and realised afterward that no, you can’t, and that given the current offer if you don’t want disc brake you have very litle choice for the wheels you can use. For now I beleive Zipp’s are the only disc wheels you can use ? Rear hubs available are Zipps and Chris king only I think.

That is very disappointing! Seems like it wouldn’t have been a difficult thing to implement either…

Because no one needs a 53 tooth chain ring and everyone needs a 10 tooth cog.

Chainring changeable quarq ftw!

As my understanding, there is no option for 50x37 in the new Force group, per the SRAM website and the latest GCN video on the groupset

As with the MTB community, XD was an open license from SRAM that would allow ANY hub manufacture to develop XD to fit their specific system. I believe that it cost them nothing to do this. This link will take you to all current manufactures that have an XD or XDR option. https://www.xddriverbody.com/ Hope this helps… the only hold out was Shimano (from my understanding). I’ll let you guess as to why :slight_smile:

you’re right. the only problem is if you have an inventory of wheels that predate the current methodology that all (except shimano) now use: replaceable end caps for QR or thru axle; and replaceable drivers.

no. 11sp. that would defeat the whole purpose of the groupkit.

there is no need for any chain ring larger than 50t. if you think you need more than a 50x10, i’m happy to do that math for you.

i don’t remember that on the lowdown i got on this group. but i’ll check and report.

Weird, Chris King isn’t on that list, but they sell hubs with XDR?

I don’t think that it would defeat the **whole **purpose. In my case I’d like 2x11 wireless shifting with the smaller blip box and the AXS software. If they were to release an update/re-packaging to their 11s groupsets then I would agree with you.

Edit:
Unless of course we are taking the cynical (truthful?) view that they want to only sell full new groupsets and not allow upgrading parts of the kit.

Great call…thinking that it’s just a matter of SRAM updating the site. Have to believe there are a handful of manufactures that have an XD or XDR option, and not on that list/site.

Is the pricing for this based in reality or is this another “trickle that shit up” moment?

the new AXS system is organic in its approach. there is not, to my knowledge, any 11t 1st position 12sp cogset for a 2x system. correct me if i’m wrong. i think eagle is pretty much it and i don’t think you want a 50t inner cog on your 2x system. that leaves you with 12sp cogsets that have a 10t 1st position cog (if it’s SRAM).

so, with SRAM AXS, the derailleurs, shifters, chain, all optimized and available only for 12sp, what 12sp cogset with an 11t 1st position cog did you plan to put on this groupset?

if you’re saying that SRAM should just have made this all available starting with 11 speeds, then it needs to accommodate you by tooling up for a whole new set of cogsets and chain ring sets. or, if it eschewed the 10t altogether, you’d have the whole crowd of folks who’d complain about SRAM’s lack of the obvious choice: a 10t cog.

what SRAM did was make a choice based on breadth. if you just to the gear inch math, starting with 10t (a cog you’ll need, but so sparingly you won’t have worn out in 10 years of everyday riding) what you’ll see is that this approach makes the most sense. the problem is that some folks have wheels from a half-dozen years ago, or older, that won’t be cross-compatible. yes. that’s a problem you and i face from time to time.

did you read my article on this? apparently not.

I’ve done that math.
Mechanical Advantage:
50/10 = 5 (higher top end)53/11 = 4.818Delta Mechanical Advantage (assuming a SRAM 12sp 10-33 cassette):
Using a 53t (mean of 0.336), going from…
13 to 12 is 0.3412 to 11 is 0.40111 to 10 is 0.48215 to 14 is 0.253 (for reference)33 to 28 is 0.287 (for reference)Using a 50t (mean of 0.317), going from…
13 to 12 is 0.32112 to 11 is 0.37811 to 10 is 0.45515 to 14 is 0.238 (for reference)33 to 28 is 0.271 (for reference)This tells us a few things:
With either chainring, the jump from 12 to 11 is a relatively large change in feel. From 11 to 10 is even more drastic.The use of a 50t rather than a 53t brings brings the jump from 12 to 11 into a more “normal” feeling range. 11 to 10 is still big, but should feel like less of a jump than with the 53t.In either case, per the reference lines, anyone telling you that gaps at the high end of the sprocket are too big is full of it. You need the gaps that big for it to feel like a more “normal” progression between sprockets.

MSRP for SRAM Force eTAP AXS = $1250 - $2000 per their website.

Is this actually cheaper than Sram Red eTap?
