SRAM Omnium crankset

I am planning to use SRAM S-300 crankset in a Curve D3 folding bike. This bike has very little room, so it is important to know the Q-factor on the cranks to make sure my heel doesn't hit the shifter cover of the internal gear hub.
Could any of you giveme an approximate meassure of what the Q-factor of this crankset is? Thanks

Ups, Sorry... the SRAM omnium I want to say.
