Could be that’s a road chainset, looks like you have an MTB. If you have a BB with a 68mm width you need one with 73mm specifically for a MTB.
I see you have a ruler, have you measured your BB?
Is a CX11 which I thought was ok.I’ve used Campag powertorque cranksets on loads of frames and never had a clearance issue
Frame is MTB disc frame from SW somewhere..More info needed to try and help. What bike is it and what crankset have you currently got on there? What crankset are you trying to fit? Power torque will fit any normal road bike - be aware that once it is on it is not an easy task to remove it.
OKThis is the spec sheet from Campag on the CX11:

if you have the English thread version shell width is just under 68mm.
Did you measure your BB shell width as I suggested? This should give you your answer.
