Bought a bike over a year ago that came with aksiums and they have been very good wheels.. Have held there true and feel very solid when putting down some torque.. I would just ride them and take them in to your shop and have the tension checked after a few months on the road.. I have the older Aksiums which are 24 spoke, the newer models are 20 spoke..
You could also sell the aksiums or keep them as backups and look at a 36 hole setup like this
