I'm not too fussed, as the wheels are for my new frame, however I was planning on riding the wheels for a while until the frame is ready.
The front wheel is fine.
The rear wheel won't fit in the rear drop-outs. The spacing is fine (130 mm) but the end sections of the hub is slightly too thick to fit inside the drop-outs.
The new wheels have Alchemy hubs. The current wheels have Shimano Ultegra 600 hubs.
Was there a new 'standard' change in rear hub/axle sizing that I wasn't aware of?
Here is a picture of the drop-out.
