When did you cut the canes down? Though unless it was well into this year, that shouldn't have caused the delay in fruiting, which should be August / September mainly. Too much feed and water? Or are they shaded? I suspect they are just being cussed.
The pruning advice on the Crocus website is:
Cut back all the canes to just above ground level each February if you just want one crop of fruit in late summer and autumn. To grow as a primocane (ie producing two, smaller crops each year), cut back the new spring stems, which have produced fruit at their tips in autumn, to a point just below where the raspberries were produced, soon after they have finished cropping. These half-canes can then be left to overwinter, will put on new top growth in spring and will then go on to produce the first crop of berries in early summer. After these two year old canes have finished fruiting they should be cut right back to their base. In the meantime, new canes will have emerged from the base of the plant in spring and these should be tied onto their support as they grow. These new canes will then produce the second, later crop and should have their tops lopped off after fruiting. This then creates a repeating cycle.
So you could try shortening the 2016 canes in November / December to get a summer crop in 2017, and that may kick the 2017 canes to fruit earlier.
