I have been riding Selle Italia Flites for more than ten years now. And I only recently started doing road riding in the last five years. I've had the Flites on all my past MTBs and have never had a problem with them even during those 10 and 12 hour epic rides on full-rigids. But again, every butt is different. BTW, there used to be a time when there was no distinction between road and MTB saddles. I guess ignorance is bliss in that sense.
