If the levers are alloy I will just skip. More expensive than Ultegra, same weight. Why would I? I am a Campy fan for lots of years but... For my good bike SR for the others either an older Chorus 11 or Ultegra/Force.
If they keep to the pricing scheme they have introduced with 12 sp Record and SR - potentially Chorus could be less expensive (street price) than 11SP Chorus and put it a lot closer to Ultegra.

As it's almost impossible to get Shimano On-line from Europe in North America anymore - it's quite possible you will be able to get Chorus from Europe for less than you can buy Ultegra here.

I like the look of the new levers better

Also when I use Potenza I always love the feel of the alloy levers & they remind me of C-Record of old.
I always wondered if they used the same dimensions


But then again I fell off the carbon bandwagon years ago
The only carbon thing I use these days is a seatpost :lol:

As for this New Chorus Groupset...
At least the pricing of suggested retail is not (too) insane so maybe when on sales might get almost reasonable

The cassette is a nice touch for the many new gravel guys or really tough long climbs

I've always liked the carbon bling on the shift levers but we know that it's probably an inconsequential 20 grams. One could always buy Chorus + Record levers. For me I'd buy Chorus a hundred times over before switching to Ultegra.

I wonder if they will come out with a Chorus "Carbon" upgrade group at some point with Chorus aluminum levers becoming Potenza 12 at some point.

Anyway, the older I get the less I care about bling, a faux carbon weave, or a few grams either way. I've got multiple bikes on 11 speed so a new bike and 12 speed is a probably a few years out for me.

Bling or not: Carbon levers are not as cold as Aluminium levers. Greetings from Norway. :lol:

Cyclingtips is saying the Chorus Cranks have a new BCD Diameter for the 48/32 rings so they won't work on Record/SR

But the Chorus crank and chain rings will work with R/SR.

From reading the cyclingtips article, it seems like Campy was a bit too conservative with some of the choices. Like:
An updated rim-brake caliper now handles rims up to 28mm-wide
People are buying 28mm tires now, putting them on wide rims where they measure 30mm+.

53/39 is not an available option.
the stated tire clearance for the front derailleur tops out at a modest 700x32mm
It doesn't sound like Campy was thinking about gravel at all. Just old geezers. :-)

OK I have a (possibly dumb) question about the brakes.

I've noticed that with Potenza skeleton brakes (and the non-series "Campagnolo" brakes, which are the exact same just with different logo) the barrel adjuster/ferrule piece actually screws into the brake arm which is threaded. Once it's in, it's in. This makes it really, really stiff. There's no movement when you pull the brake lever and hence no room for any loss of brake power/modulation.

On the more expensive brakes (C/R/SR) that piece kind of just "sits" into the brake arm (there's a little "male" ridge on the under side of the ferrule piece and it is supposed to seat into a "female" shape) and the whole mechanism is only secure once you thread the brake cable through and lock it in with the nut. This introduces a lot of play at that point and when pulling the lever that barrel/ferrule piece actually moves which is wasting your braking energy.

Net result: braking power, modulation and feel is WAY better on the cheaper brakes.

(or have I been putting this together wrong all these years?)

No, there is no loss of braking efficiency as a result of that. The stop is a stop, a hard stop. Super Record brakes are still the smoothest operating caliper available, bar none.

One thing to be aware of - for those that like to save a few quid using a Chorus chain with SR/R - from road.cc:

"The new Chorus-level chain weighs 13g more than the Super Record/Record chain, and comes with 110 links as opposed to 114 because you won't be needing the extra links with a maximum chainring size of 52/36"

No 53/39 for chorus - so no luck with running a Chorus chain if you have those size rings on one of the higher gruppos.

Assuming the 12sp FD have the same or more clearance than 11sp - there should be lots of clearance - I am running a Potenza FD with 700x42 - lots of space on my Gravel bike.

But then Gravel bikes tend to have longer Chain stays so this is not an issue. The chainstays would have to be longer than ones for a 700x32 tire (or the tire will rub) anyways - so there should lots of room for gravel tires.

If you think you want to use bigger than 28mm tires, then forget rim brakes and just go straight to disc. There’s gotta be a cutoff somewhere. I think 28mm on a road bike is it.

Cal, when I saw a pair of the non-series brake calipers on someone elses bike I noticed that difference, bought a set for myself, and installed it one of my two bikes. Both Canyons with the same geometry and setup - one Ultimate SLX alloy and one Ultimate SLX carbon - both running Chorus. I put brand new Swisstop blue pads on both and switched my Zonda's between the two. Then put on Campy red pads and switched my Bora's between the two.

The difference is astounding. Like night and day. Have a good look at that ferrule piece on a set of C/R/SR brakes as you pull the lever and engage the rim. It moves! Which means it's losing power and the "system" overall isn't as stiff. Nowhere near as stiff, actually, as the threaded system.

If you're bored, give it a shot and see. They're cheap, and the logo says "Campagnolo" in the black-on-white logo that complements Record/Super Record nicely:

Yeah I was thinking the crankset would be the star because truthfully the rest is not impressive low weight wise
even my Potenza brakes are 15gr lighter

But yeah :noidea:
