Hello. I just bought a 2012 Scott Foil with Ritchey Seatpost. I am trying to replace the stock saddle with my Selle Italia Flite Gel TI saddle but looks like the saddle rail is oval shaped and taller than the stock saddle (Selle Italia X1). Could somebody please tell me what Part No. and where I can order the right 1-Bolt clamp for this. Thanks.
