Pretty close, but the 44/51 will be slightly easier

44/51=0.863
40/44=0.909

It comes down to how fast you gonna roll them flats/long downhills

I feel that if you’re going slowly up hill to need that 51, you may need that 44/10 to pedal downhill. If it’s flat/rolling fast roads or gravel, I found 46 10-44 to be an awesome gear.

Is that Shimano? I can only find SRAM with either 36 or eagle. I'm considering the TRS plus 10-46.

The Sunrace cassettes are pretty good. Don't buy any of the off brand ones on Amazon. I made that mistake once

Yep, I have a few in 10spd and 11spd and all performed well. They also have different grades, some are heavier than the NX while some just a tad heavier than the GX cassettes. Though I haven't bought an XD version yet.

I just realized these sizes may not work. I have two Rival setups I'm deciding between. Either a 40/1x11 mech or 2x12 axs. I just picked up a 43/30 Rival crankset used as a starting point. I'd prefer to get the AXS setup going as it's going to be my 'daily' ride in 2026. Are you using Shimano and is yours a 1x12? Stat sheets say max 36T for Rival AXS but I've read many about people using 42T just fine. Also came across two new terms that I've been trying to ignore, Transmission and Xplr. Any of these need to be considered? My frame has hanger and I'm not on 13 speed.

Transmission is the latest mtb axs for udh hangerless mounting.

Xplr is similar

But do cassettes marketed as Xplr work with non- transmission setups? I see some with ranges which work with my options. What about 2x?

I debunked that transmission chains wont work with a shimano cassette (they do) so as long as it is the correct number of speeds, it will work. any of the non compatibility stuff is marketing.

You can use stuff above what the largest ring says, however you will grind out your derailleur and you will need to adjust your b out of wack so it will make it shift like crap.

From my budget project two years+ ago.
MTB cassette, road link, new cable and chain.
works* great.

Thread 'SuperX for Gravel GravelX !'

So i have this really cool 'cross bike, which i picked-up form @xc62701 -
everything works - super light, fits well.

BB30 with cross gearing - not great for gravel. The chainrings are "close" 36-40 ???
and the cassette is small - 12-27 ?

Sram force equipped.

any ideas of a path to 1x ?

*I did ride it this year. hopefully more in '26.

New xplr is 13 speed. The previous gen xplr is 12.

@stb222 transmission and road flat top? I’m pretty sure they are the same.

, i havent had a reason to check of the road and transmission flat tops are the same but it would make sense that they are. Maybe different pins?

I have never been a fan of sram chains, always seemed loud and chunky shifting compared to kmc andshimano, but the flattop ones are really nice/work well.
