The levers on the Bontrager skewers are shaped very differently. I like the shape and the way they feel when you flip them -- there's something sturdy about it. But you're right, they don't fit in a trainer. On the other hand, my mountain bike has old Shimano skewers and they are very similar to the one that I got for the trainer.
I guess this is one way that wheel manufacturers try to differentiate the look of their products vs their competitors. But many of us are riding around with Cycle Ops skewers on our fancy wheels anyway.
