Besides the reported 55/40, will there be any other "new" chainring option, or will 50/34, 52/36, 53/39 all stay in place?

If there's 55/40, I could see them getting rid of 53/39. Most current 53/39 buyers will probably go for the biggest option available.FlatlandClimber wrote: ↑Tue Aug 03, 2021 1:04 pmBesides the reported 55/40, will there be any other "new" chainring option, or will 50/34, 52/36, 53/39 all stay in place?

A bigger jump between big and small ring is always welcome for me, at least as an option. Something like a 52/35 or 51/34 would be welcome. However, I doubt they will go super unconventional.

Someone posted the chainring size options many pages back. I believe it was 50/34, 52/36, and 54/40.
I'm current running a GRX 48/31 crank and a 11-32 cassette and love it. However my 9150 FD wouldn't shift the 48/31 properly so I had to change it to a GRX FD. A 48-11 is a taller gear than a 50-12 and it's fine for me. A smaller large ring puts the chain on the taller end of the cassette where the tooth count gaps are smaller. If a pro is fine with a 54-11 I'll be fine with a 48-11. I'm down 200w or more from a pro.

Surprised they haven't done anything visually (color) to distinguish it from the last iteration. Coffee shop crew are not going to be happy rolling up and nobody can tell you have the new stuff, what's the point.henau212 wrote: ↑Tue Aug 03, 2021 2:52 pmAlso, new Agree (links seem to be working from time to time..):Addict15 wrote: ↑Tue Aug 03, 2021 1:59 amEmbargo for new Dura ace will apparently be lifted 31st of august -> https://www.cube.eu/nl/2022/bikes/road/ ... lverngrey/

You will never see this. You need small as possible jump, hance everyone use 53/39 more than 52/36. With 52/36 when you switch front chainring you need AT THE SAME TIME double gear switch on the back to get to the same ratio. With 53/39 you only need one, so it is a lot smoother and faster and better momemntum. Sram get even lower 13T jump.FlatlandClimber wrote: ↑Tue Aug 03, 2021 1:35 pmA bigger jump between big and small ring is always welcome for me, at least as an option.

Pro team bikes might be another story, but are you sure that more consumers use 53/39 than 52/36? In fairly mountainous areas very few people are still using 53/39 in my experience, because with 52/36 you can get both a top gear that's almost as fast as with the 53, and reasonably easy climbing gears at the same time.Minirac wrote: ↑Tue Aug 03, 2021 8:45 pmYou will never see this.

Also, looking at bike catalogues, you usually see 50/34 on lower end and endurance bikes, and 52/36 on the racier builds. But very few bikes come pre-built with a 53/39 these days.

While I don't want to speculate on amount of people using whatever, I will say that after using SRAM with a 13T jump, I much prefer it over my old 52/36 set up. The double (or more) compensation shift I always felt put my chainline in a less than ideal position. The 13T jump allows me to stay on the same side of the cassette block that I need to be for good chainline.Minirac wrote: ↑Tue Aug 03, 2021 8:45 pmYou will never see this.

Does anyone know if the cassettes will be compatible with other 12s cassettes, like Rotor, SRAM, or Campy? That would be nice.
Also, the 105 Di2 is hilarious if true, given how many people on this forum mocked me a few years ago for saying I'd like that and said it made no sense and would never be made.

With a narrow range cassette (11-25, 11-28) you'd be shifting the FD more often to keep a good chainline. However the new trend is wide range cassettes. With a wide range cassette you can stay on the big ring longer, and only shift to the small ring for extended climbs. You see it in the pro peloton. Riders prefer riding on the big ring despite some cross-chaining. A 17T tooth gap is a good way to extend the range. I'd love to see a 50/33.Minirac wrote: ↑Tue Aug 03, 2021 8:45 pmYou will never see this. You need small as possible jump, hance everyone use 53/39 more than 52/36.

For pros, small jumps are perfect, I get it. But 39 just is too big for riding steep long climbs, like in the alps.
It's not that you can't make it work, but it is not fun.
I am currently in the Alps, and have ridden several of the famous Cols of le Tour, with gearing going as low as 1:1. it is a dream on long rides, and with >5Wkg FTP, I am not the weakest or heaviest cyclist. I am not using the 1:1 gear super often, but it's nice that it's there.
39/32 will be a big gear to push for non pros on Col de la Loze, on the steep part begins AFTER 1300 meters of elevation gain.
