Amazing that Specialized answers a link. I am in between saddles and had loved the ruby but again trying the aspide glamour to see if the cutout is causing the chafing I get. I was told the romin is super hard and didn't even think about trying it. Good for riding in the drops but not much else. Arielmoon have you looked at something that is flexible around that area like a SI SLR or max flite? I have uneven hip bones from a horse wreck and always look at the flexiblity of the area around the cut out where my rami bones hit. The new ruby expert is a litte more padded and is flexible. I will probably end up going back to that.
