Cyclingtips discusses the differences between Force and Rival:
https://cyclingtips.com/2021/04/sram-rival-axs-review/

There are some differences between them: Rival controls do not have the expansion ports for satellites, the adjustable travel for the levers and also the bleeding-edge-port in brake calipers is replaced with a simple port.

Another difference is that Force and Red shifters can now control legacy 11 speed eTap derailleurs thanks to a recent firmware update.

I think you're right on the money as far as value to weight ratio is concerned with this build. When I built my Force group up it was clear that the cranks and cassette are by far the best way to save weight on an AXS build.
Im looking to do a build and was thinking going Force for FD/RD/shifters, Red for cranks and Rival chain/calipers and cassette for high wearing parts.

I dont think I could afford the Force or Red cassette and chain in the long run especially when Shimano and SRAM are divorcing with compatibility. This sucks for us consumers. Has any 3rd party company made any AXS parts?
I think the best Price to weight ratio for AXS is as follows:
Rival Shifters
Rival FD (nearly as lite as Red and lighter than Force)
Force RD
Force cassette (Rival cassette is really heavy)
Red Crank arms (cant beat 355g arms)
Chain Rings Red or Force, whatever is cheaper, they are really close in weight
Chain Force chain is pretty good for $35 USD
I quote your post because I am in the middle of a crisis here :lol:

I bought a aspero frame 1 y ago and very slowly I am building my bike. At the moment I have a For e RD, Red crank arms, chainrings .... almost done the transmission except for the shifters and brakes. I wanted to go for the Force but it is almost impossible to find. Now the rival shifters are available somewhere and I don't know what to do: waiting for the for e.or go for the rival? It's mainly a psychological thing, my dream was to build this bike with premium components and I did not want to go for "budget" stuff.
I totally understand what you are going through.. I have Red on my Aethos and Rival shifters sitting in a box for my next gravel build.. The Rival looks and feels so nice, much more compact than the Red or Force.. But I under Wanting premium.. Just no there is only 20 grams difference between Red and Rival shifters hoses and calipers included... also if you install aluminum backed brake pads you will save another 15g per caliper making it lighter than Red with normal pads..

The Rival FD is a dream, Inthink Sram secretly redesigned it as I have experienced 0 shifting issues unless I do something stupid like shift small to big when im below the middle of the cassette

My force FD will shift from small to big with the chain anywhere on the cassette. Most problems come from the marks not being parallel to the big ring.

I know that, but for whatever reason I found the Rival FD to be a bit smoother and more forgiving.. also the redesigned cage on the Rival makes it super easy to align all the hash marks; much easier to read for me..

Unfortunately I lost the train. The shifters were available only for few hours and I thought about too much .. I have to wait for the next batch... When? I don't know :noidea: :(

Some German shops list the availability for Force AXS levers as six weeks (bike24), some shops as in March 2022 (r2-bike). :x

Does anyone know if the Rival shifters have the same rattle issue that some other Sram shifters do? My older Apex 1 Hrd shifters are terrible in that regard, there is so much play in the brake levers that you have to keep a finger on them at all times to avoid rattling (unless you really turn the reach screw which makes the distance to the levers too big for me). Guessing they have improved this, but want to hear some real world experience.

I just tried Rival levers and I have to admit that they feel better than my Red...

Shift buttons have a much more positive action that feels closer to Di2 than Red/Force's mushy mouse click. Brake feel is about equal between the two, maybe a bit heftier for Rival due to the levers being alloy instead of carbon?

To be honest, I am using Rival AXS shifter and brakes since 2 weeks now on my new Festka and I am coming from Red Etap and Red AXS. No need to use the more expensive Force or Red parts concerning shifter and brakes. Crank, Cassette, Chain I am still using Red, because of the weight.

I wonder about setting the lever reach to the closest position and still having enough lever travel with no contact point adjustment. I currently use Juin-Tech GT calipers and force axs mechanical levers set to the closest position. Contact point adjustment is done by turning the cable tension knob. No problems.

just want to add to the pool. after experimenting with rival, force and red AXS rear mechs (more than one of each). i found that rival rear mechs do not play well with non-round rings (i tried rotor AXS Q rings). it seems like the Rival clutch doesnt cope well with the chain/chainring bottom engagement point constantly being moved up and down. This effect is also observed with shimano clutched rear mechs. no problem with force and red rear mechs.
Some say pour 10ml water out of your bottle to save that last bit of the weight. Sorry, i go one step further, i tend to the rider off my bikes. :thumbup:

That is good news. The availability of Force levers is quite bad, so I will now keep my eyes open for any good Rival lever deals. The weight difference between them is minimal.
