Will be curious to hear Deb's thoughts. The nice thing about leather saddles is they can be slippery so less pressure points. If cleaning doesn't help, personally I would tip the nose up a hair - if you are sliding off the front that is. If you are sliding off the back, I'd move the saddle back. I know you had a fit but there is always room for micro adjustments. Also Deb says no need to treat your Rivet leather with anything so perhaps wiping it clean after every ride with a damp cloth. keep us posted
