It was up on there website - Now it's gone.

I think I remember it being 278 GRams for the CRank arms and Axle - Isn't that 30-40 grams lighter than the old Clavicula? Add some Bearings/cups/rings - wouldn't that put it solidly under 500 Grams?

More importantly, I hope they reduce the Q-Factor from the Clavicula model.

I think it said the Q factor is 148mm so 4mmm narrower than before.

And the new crank is good for 120KG.

Weird they include the bike mass in the limit.

SRAM Red claimed by Art's is 512 grams for 50-34 BB30:
http://www.artscyclery.com/Sram_Red_22_ ... RECB2.html

That's without bearings, clearly.

They don't have a weight for the 110 BCD GPX, but if the delta is the same as the 130 mm, it would be 564 grams.

But SRAM Chainrings are heavy. They got bit early in SRAM Force days with flexy, but weightweenie friendly rings.

126 grams for the 50:
http://www.artscyclery.com/Sram_Red_Yaw ... 0110B.html

But only 28 grams for the 34 (very nice!)
http://www.artscyclery.com/Sram_Red-For ... 3411B.html

That's 154 for the rings, taking the crank w/o rings down to 360 grams.

So looks like this one saves around 73 grams relative to the BB30 SRAM, 125 grams relative to the GPX SRAM (using delta below).

Note SRAM claims 557 for BB30 and 609 for GPX.... but that's 130 mm BCD:

The THM bearings if unchanged will weigh about 93~94gm.

So these will weigh about ~380g including BB, excluding chainrings. My compact Clavicula's came in at ~415-420gm without rings if my memory served me correctly.

SRAM Red rings are 154 grams. My Praxis 46/34 are 139 grams (way heavier than I expected, BTW). These are top-shifting rings. The total with the Praxis would be 520 grams + bolts. Still impressive! My Lightning with SRAM Force rings is 581 grams.

I'm just guessing here, but they might be trying to keep things consistent with how they calculate the weight limit for their brakes.

60 grams lighter than the current Clavicula classic. That means with a BSA bottom bracket, chainring bolts, and Praxis rings the complete setup should be 495 grams. Using Extralite rings the complete setup should be right at 460 grams. Clearly the lightest on the market, but it will come at a price. Expected to be about $1700 USD.

Q-factor is indeed reduced to 148mm. We're expecting to see the first ones in April.

Wow. So is that in compact or 130BCD? What BB configs do they come in?

For bb standards, it's important to note that it's not compatible with all, but is compatible with most. It works with most common bb standards with one major exception, it is not for bb90 which unfortunately eliminates Trek bikes.

Look good! Not sure I can see Trek continuing with BB90 for much longer - so many cranks that work with all BB designs except BB90!
