All-weather performance was not a consideration.

And for generally discs work great on bikes. I don't find stopping distances to be amazingly better in the wet ... just more immediate. Still, they are better for most general uses.

Again, the issue is not general use, but the safety factors involved with using discs in a pro peloton.
