I'm curious if the new Red22/Force22 cranks have a long enough spindle to fit into a standard frame. It seems to share the same design as the S950/S951 as opposed to the older one piece design of Red and Force... just curious if the spindle is the same length as well. They say it fits BB30, PF30, and BB86... which leads me to think the spindle is long enough to accommodate any frame design out there right now.
Thanks,
Greg

I just installed a BB30 SRAM Red 22 crank, and it seemed like standard BB30 length to me.

I have an S952 crankset, which i think shares the same design, and it definitely has enough spindle to fit a standard frame.

The Red22 BB30 cranks I just looked up on the internets don't look like the S95x cranks. They look like the older Red BB30 cranks. The DS crank arm includes the spider rather than the spider being separate like on the S95x. And one chainring bolt is in the crank arm like the older Red cranks.

I'd measure before buying one to fit a BSA frame.

Sram S952 cranks share the same dimensions as the sram red/force22 cranks.

Correct me if I am wrong as I have not messed around with the new Red22 Crank.

The BB30 Crank will fit BB30 and PF30 frames.

The GXP crank will fit BB86 frames. GXP can technically be used with any frame and BB standard, you just need to get appropriate adapters.

SRAM Red 2012 and Red 22 BB30 cranks fit in a BB30 or PF30 frame. Not long enough to fit in anything else.

Those specs don't include the spindle length, which is the issue here.

Force 22 BB30 has a spindle length long enough for BSA threaded/BB86. Red 22 BB30 does not.

Any of the BBRight/BB386 cranks should offer what you are looking for: http://www.bbright.net/images/whybbright/slide15.png

They're not listed on the chart, but the Quarq cranksets - Riken and Elsa - have the 30mm wide/GXP length spindles.

It seems that in almost all cases, SRAM cranks with removable spiders have enough spindle length to work on a threaded frame. Basically all of these cranks will use a large spacer (on the drive side - from memory) which isn't present on Red cranks or any of the earlier models with a 1 piece arm/spider (because the spindle is much shorter). Removing the extra spacer and changing the preload setup can give you enough room for the external bearing cups or the extra width of other press fit BB standards.

From memory there is a thread with decent pictures on the Cervelo forums. It's about using a Quarq BB30 crank on BBRight but it's basically the same process. Keep in mind the Red Quarq is not really a Red crank, but just another set of S9x series arms with a removable spider.
