I definitely agree that it looks better especially compared to Force. No way would I put a crank with a plastic cover on it near my bike. The hoods look better and for the price, if the functionality and manufacturing is decent (assume in China) I could see this being a popular group.

I think we will see many gravel bikes with Rival AXS levers & brakes and Eagle GX AXS rear derailleur.

Definitely. Sram is also selling it aftermarket as a bundled mullet groupset.

Curious, what is plastic on the Crankset?

A 48/32 11 speed crank should work since I'm having perfect performance with grx 48/31 and 46/30 cranks. Never a chain drop. Both of my force FDs want to rotate a little during the final tightening of the clamp bolt. I carefully measure the gap between the crank and tail of the cage, with the bolt lightly clamped. I always have to add some clearance, to get the cage parallel to the rings, with the clamp bolt fully tightened.

A Campy chorus 48/32 also works.

Both force and rival have decorative plastic covering the chain ring mounting bolt areas. Some cranks have developed cracks in the plastic. Shimano grx cranks aren't as pretty, but they work well. They have exposed bolt holes for the big ring. The wider chainline is easily corrected, but they do have a wider 151mm q factor.

1400$ for a third tier groupset. This hobby have gotten silly.
I think that's cheap, considering you have folks on this forum dropping $400-500 on a single seatpost.
I don't see how some folks dropping $400-500 on a seatpost makes it any more justified.

Considering that this is effectively a $3k groupset technology trickled down to $1.2-1.4k price point, I'd argue that that's cheap. If we wait, these groupsets get discounted even further. Pre-pandemic, Competitive Cyclist would discount a Red hrd groupset w/o cranks for around 2k; Force hrd w/o cranks would be discounted at 1.5k. If we were in a normal supply chain situation, it wouldn't be farfetched to see this groupset priced at 1k after discounts. For the technology you're getting at that price point, I'd argue that's still cheap.

Now if you're arguing that bikes are just plain expensive, you're right.

There's a black plastic cover on the outer chainring according to the Cycling Tips article. Must be the area in the center?

I might have skipped over this but is the "wide" chain line a different version of Rival AXS such as Force "wide" with a different front derailleur or are they referring to gear range being "wide"? For gravel, I think the extra 2.5mm Q factor to get tires to 45mm is important and would just use that as a benchmark.

Dude, there's nothing cutting edge about a very cheap wireless transmitter and small electric motors. The cost of the electronic brifters and derailleurs is down to massive margins, not huge costs - sunk (R&D) or production/BoM.

Agreed. My bet is that electronic drivetrains are already cheaper for the manufacturers than mechanical ones. Add bigger shelf price and you have double profit.

+1

This happened in the camera market years ago. Precise mechanical components are expensive to assemble and QC has to be spot on. This keeps costs high.

Manufacturing innovations for assembling digital components are easier to find and will result in lower prices (higher profits).
