I tried to search and could not find. Give me a number and this will go away.

Thanks!

It's not an angle. It's a measurement in mm.

There is not much difference in the major brands which fall in the 145 - 150 mm range. See here http://weightweenies.starbike.com/forum/viewtopic.php?t=63682

I had the SRAM specs once but cannot find now. Their BB30 and GXP cranks had the same Q-factor.

Q factor, yes I was still working on my first cup of coffee. The general consensus is that both the BB30 and the GXP on older Sram is 150mm.

If I'm not mistaken, it's 149.2mm for the GXP version and 145mm for BB30. The newer GXP cranks have a Q-factor of 145.3mm

Maybe. Backup?

There is no inherent reason why a BB30 crank would be any different than a GXP crank when it comes to Q factor.

Here's one example from SRAM

OP is talking about ’10 Red cranks.
