I have an older cyclocross bike I'd like to refurbish with a new frame. I'd like to replace the road cranks with mountain bike cranks, probably LX and a 44-32-22 chain ring. If I read the Soma web site correctly, it seems the double cross will only take road cranks - is this correct? Does anyone know if it's possible to set it up with 44-32-22 chain rings?

Thanks in advance.
