different bike - 1x gravel with a 46T crank and 10-50 cassette (cogs: 10-12-14-16-18-21-24-28-32-36-42-50):
a lot of time in 2nd cog. And I spent 80 seconds above 30mph, so 46x10.
Speed over those 8 minutes:
and cadence:
here I would have preferred the 48x35 2x of my road bike, although this gravel bike will fit a 50x37 according to Trek. But its a gravel bike so the 46T with 10-50 is a good compromise as it gives me lower gearing for gravel climbs.
Thanks - this is good info! How do you see the time spent in each gear - would be curious to look at my data.
Iām using WKO5 but you can use axs.sram.com if your bike computer is recording gear shifts and syncing to axs.sram.com
however you canāt select any segments, its just a total.
Just added that to Intervals.icu using Custom Chart / Streams. Here is a short segment from last night where I pulled for ~3-minutes at 22-28mph in 48x13 (started 48x15):
a little tempo joy ride, and I swear its faster solo when 9 people arenāt behind me blocking the wind!
And later, in the opposite direction averaging 12mph in 48x24 at 189W 
just settle in and suck it up 
I didnāt know you could do that in intervals.icu ! Thanks for the tips!!
Click Charts and then CUSTOM STREAMS
On CUSTOM STREAMS click 
STREAM and search for āgearā and add them:
I donāt know what youād consider a hilly race with a TT bike, but couldnāt you just get another rear cassette. For reference, I have run 1x on my aero road bike and I used to live close to proper mountains. My 10ā36 cassette was just fine. Of course, I did not put a 54-tooth chainring on it. 
Iām living in a very flat area and I think I will do more than ok with a 10ā33 cassette. I got one when my cassette on my trainer wore out and I will swap them soon. I might also get a bigger chain ring (going from 42 to 46), although Iāll just see how well my 42-tooth chain ring works.
I know I am late on this, but were you still interested in parting with those 54/41 rings?
Ok so I sort of went down a rabbit hole then went on vacation and got busy at work so just coming back to this.
I bought this bike 2nd hand not realizing that the giant rings came with a derailleur. One thing I canāt figure out is that if a) there is a difference from the regular FD and b) if so if my bike has the FD made for the big rings.
Does anyone know how to tell? Is there actually a difference?
I do know the difference. In short, on the original Red Axs stuff, it was only made for rings up to 50t. Because of the UCI commercialization rule, they had to offer the āpro sizedā rings in 52/39; 54/41 and 56/43. In order to do that, there is a different red FD that you could only get with those rings (which is why they were like $1500)
Basically there is an extra hole below the normal hole and a wedge that will push it back a few mm to allow the extra room. This all went away on the newest red stuff just released, there is now only 1 derailleur size. I happen to have a regular force one and the red one with the extra hole ad put pics below.
I kinda left @lwcaron hanging since I couldnāt figure this out before. Iād still give them first crack but weād have to work out some sort of FD swap. If they are not interested then you and I can make a deal.
Correct you have that derailleur AND the FD you have can be used on the big or small rings. I always thought it was dumb they created an extra sku just for that small hole and shim.
For rings for yourself, I would recommend the Force 50/37, its half the price of the red stuff and its the same weight just in black.
The fact that SRAM makes a different FD comes as a surprise here. The standard model can work with chainrings larger than 50t. Whether or not it is optimal is a question. I wanted larger gearing when building my current bike two years ago and found at time that Praxis rings were compatible with 12sp AXS Flattop chains. I set it up using a 52/36 Praxis rings and found shifting to be perfectly fine. May have been dumb luck.
I also knew a handful of guys who ran a Rival FD with Praxis rings but it all depends on your Front Derailleur Hanger and how high you can bolt in the FD on that hanger (if its braze on) if its not then you can just raise the collar
How/where do you buy the āproā rings in 56/43? On the SRAM website it only shows up to 50/37.
Try this page:
(deleted - old model)
has all the pro sizes, those include derailleur and integrated power meter.
Iāve never seen chainrings only, have searched in the past and never seen. You might want to contact them and ask.
Prior to this most recent red release a few weeks ago, you could only buy the āproā sizes with the front derailleur.
With the new red, you will be able to buy the larger rings separately in power meter version only ~$800. I think the eta for them is mid summer
I am trying to convert my SRAM Force AXS to 52/39 front and 10-36 in the rear.
I am thinking about using this chainring set from Pass Quest: SRAM FORCE 107BCD-Quarq 2X Sprocket AERO Road bike Gravel bike 12s AXS ā PASS QUEST along with this piece for running it with my sram cranks: PASS QUEST Adapter Converter for FORCE 8 bolt to X110BCD AXS12-Speed
I wan wondering if anyone could help me with the following questions:
Any help you can provide will be much appreciated!
Having issues with these chainrings
It doesnāt fully bite from small to big. Any solutions?
I donāt know how committed you are to these aftermarket rings, but Iāve never been able to replicate OEM shift performance with aftermarket rings on 2x setups. Most of them donāt have the same ramp/pin design that the OEMās use to optimize shifting (in particular the small to big shift). Iām not saying you canāt get them working, just saying you might end up disappointed if you expect them to shift as well as the stock SRAM setup. Just sharing my experience from trying many aftermarket flavors in the past. Some work ok, many totally suck, but I personally never found any match OEM performance. But I also have zero tolerance for mis-shifts and dropped chains, many would be totally fine for non-race applications. Itās probably been 7 years since I gave up on them, so maybe there are better options these days. No experience with that brand, good luck.
