I’m definitely of the opinion that saddle + bibs can work as a system.
I had a different comfort issue that was solved by a new saddle and Assos shorts. Assos has a unique pad that might help with hemorrhoids. Their pad creates a space along the perineum.
I’m to the point now where I can’t even ride my old Pearl Izumi shorts. They feel like torture devices now.
Are you sure it’s cycling that is exacerbating the problem?
