I don't this 1st gen exogram cranksets had removable spiders. Doesn't look like it from the pictures.

If you aren't planning on using a powermeter, the integrated spider cranks are significantly lighter. And not that much more expensive to my knowledge.

depends how much the removed spider weighs but ....

would be interested how it stacks up with Force....

ball park numbers/estimates
470+130 (power spider)+160(rings bolts) is not far off what i think a P2M Force would weigh (i think).

for reference Rotor 3D24+P2M+Praxis (compact) = ~800g

I can do some weights soon. I have Quarq Red and P2M on Force cranks and I have to swap some things around.

My Red DZero was only 10-15g lighter (forget what spacers I had on when I weighted them.

This one is BB30 130BCD 170mm ams. I thought they would have been significantly lighter.

I'm going with a standard threaded BB. This BB386 with a longer spindle will allow me to run it in a 68mm shell with threaded BB386 cups. I'm more then likely gong to get power sooner then later.

This BB386 setup with extralite rings Is going to be around 60g heavier. That's comparing it against a standard gxp exogram with the same rings.

I made the mistake of getting the BB30 Sram red cranks before I got my Dzero with the 386, the whole ordering thing got quite confused and they offered me a return no worries, but after expensive postage back to Germany from Australia I decided to keep the chainrings and sell the cranks. So I'm now left with a brand new in the box set of 172.5mm 130BCD BB30 Sram red with etap graphics integrated cranks. I'll use the chainrings for the Dzero when it arrives, but if anyone want the cranks I'd be happy to do a sweet deal on them to a good home. PM me if you need them.

I know our supplier has them in stock through the shop I'm at. Mine are 172.5 110bcd the SRAM part number is
00.6118.446.002 their description says its exogram but it is in fact not.

Yep, they are not Exogram. You can tell by looking at the NDS arm - it has that little metal lip between the arm and the spindle. The Exogram cranks do not have that. (See the picture Deek posted of the 371g set of Red 22 BB30 cranks.)

i wonder if the "power ready" removable spider works with P2Max Sram. I think not as the DZero cranks have different attachment : (

Exogram just means hollow carbon. All of the Red branded cranks are hollow but the design of the removable spider ones is much heavier.
