I guess this means that the given frame weights by Spesh are for the raw and unpainted frames 🙄.

Good marketing this is ...

Frame weight summary

Claimed frame weight by Specialized
725g | 56cm | S-Works Crux (12R)
825g | 56cm | Crux (10R)

Actual frame weight
747g | 54cm | S-Works Crux (12R) | Satin Brushed Liquid Silver/Gloss Black/Smoke Marble/Gold Diamond Dust
780g | 56cm | S-Works Crux (12R) | Satin Carbon/Spectraflair/Gloss Abalone
790g | 56cm | S-Works Crux (12R) | Satin Brushed Liquid Silver/Gloss Black/Smoke Marble/Gold Diamond Dust
860g | 52cm | Crux (10R) | Satin Dusty Blue/Ice Papaya // Fork: 400g
870g | 52cm | Crux (10R) | Gloss Coral Lilac Fade/Carbon/Limestone/Papaya/Grey/Black

Looking forward for more input :beerchug:
@legpower, does the 747g include the rear der hanger, seatpost clamp, and bottle cage bolts? Just want to make sure the weights are all comparable. Not sure what the "standard" should be.

I was able to get my 780 listed above down to 740 without the rear der hanger, seatpost clamp, and 4 bottle cage bolts (forgot the 2 under the downtube). Left the tiny fr der bolts in (not the ones used for a 2x build), as well as the plate on the downtube for mechanical builds. As @ryanw has pointed out, there is a somewhat beefy chainstay protector and a thinner sheet of protection for the downtube, so I don't think the 725 is unreasonable for a truly naked frame. I've seen worse from Spesh-one of my ex-frames was the infamous Tarmac SL6 Ultralight. Amazing how far we have come-this Crux disc frame built for gravel is lighter than that top of the line rim brake road frame from not too long ago.

If you were able to get your frame down to 740, I think I need to reweigh mine. I removed the seatpost clamp, rear derailleur hanger, all six bottle cage bolts, and the plate on the down tube. The only thing I forgot to remove was the front derailleur screws. And still I was at 790! I get that a size 54 will weigh somewhat less, but 43 grams? Does that seem right, especially when the satin carbon comes in at 740 in the same size as mine?

No need to be rude. I never saw your previous post. I do find it odd that no one has mentioned this besides you.
It's because he's wrong. ITA shells maybe wider than BSA, but the total width of an ITA BB is not because the cups are thinner. Just out of boredom I measured a couple of setups today and an installed ITA shimano BB was actually 0.5mm narrower than a Shimano BSA.

So while he might have got away running 2mm of spacers on a shimano crank it is not designed to work like that, not for ITA or anything else.

I'm going to hazard a guess and say it'll be awhile considering frames are backordered to Q1 of 2022 last I heard.

My bike shop has no idea when my Crux Pro will come in, but it's a smaller shop. I ordered it the first weekend it was available.

As a data point, Erik's Bike Shop (of Chicagoland area) website is showing delivery of the Crux Pro in 12 days....so who knows?

I'm looking for a 61cm Pro complete and a local shop to me has a 61cm S-works complete....tempting, but not really sure I want to spend 4k+ for the S-works complete....especially when I like the colorway of the pro better....ohhh, and I'm no lightweight so not sure the weight difference matters to me (probably shouldn't say that on the weight weenies forum).

Found someone on Instagram running a 50/37 on his new crux. Waiting for a response to see if he had to do any mods/spacing.

What is the real difference between the Fact 12 frameset and the Fact 10 one besides the weight?

Besides, this is WW where we spend too much money to make our bikes lighter instead of drinking one less beer the night before! Haha

It's the hobby where 6.79makes you a lot happier than 6.81 even if it meant paying 10,000 instead of 4,000 😏

Since they quote 100g difference, it would be funny to walk up to some one with the S-Works and be like, is that an S-Works? Then squirt out some water in you bottle and be like, look I have one, too. 100ml = 100g.

The 10r frame doesn't come with a seat post.

This is a 34t, pretty tight clearance.

Confirmed the 50/37 works with the owner on instagram, but there are limitations to the width of tire. He was running 30c tubeless road tires that probably measure a bit wider without issue. I wonder if it has to do with spacing of the sram dub bottom bracket / crankset versus the SRM you are using. It's all about trial and error at this point I guess...
