Hey,
Triple front crankset will be an challenge. Its doable but hard to set up correctly.
Go for double crankset with mid compact[53-36]
Pay ateention to the fact that the seatpost in Loop is megaoversized, wicth means its 41mm diameter.
No Clamp on derrailer will fit there.
So for front derrailer you will need to get dahon front derrailer hanger for MU frames.
You will also need the front derrailer braze on model, to pin to front derrailer hanger.
I also would choose better components, like tiagra front derrailer braze on for front. It isnt mutch expensive and its way mutch better.
