Harder than wood, actually. I use a CF saddle, which I find comfortable, but the odds that one would find any individual saddle comfortable are low. Suited for a relatively aggressive riding position with less weight on the butt.
The 7x9mm rails will not fit all saddle clamps so check for that.
Edit I find it unlikely that any pros would change saddle for other than time trial. I use mine for all road rides including long &multiple DCs. The CX bike saddle does have some padding, 'tho. Do love the 100g weight.
