Yes,

However; II was meaning in the way that if you buy a car, you get an auto vs manual (you paid for it, why should you have to do any extra work, more of a UK vs US thing),
and clarified with saying 'electronic shifting', of which there are only 3 types currently available, EPS, DI2 and eTap.If your budget is in the area of the Propel, (given it's a Shimano equipped bike) would be looking for DI2 shifting, not mechanical.
