I'm just wondering why anyone would ride a modern saddle...[/QUOTE]
For one, modern saddles save weight (less to drag uphill for us old guys); for another, all tushes aren't created equally
I did 90 miles yesterday on a vintage rig outfitted with a Flite Carbon saddle (the full carbon shell type). No problem; BTW, this was my first long ride since returning to the USA after a year over in Afghanistan. Because the CF flexes, it's very much like the feeling of a broken in full leather saddle.
Good padding in the shorts helps, too!
