Welcome, and certainly search for the saddle info on this site. It is good to keep in mind that not all cut-outs are the same where the size/width/length of the cutout is concerned. For me the Diva was MUCH too large as far as the cutout was concerned but the SI Lady was just right. There will be some trials involved to find out what works best for your body. You might want to check at your local bike stores to see if any allow a demo trial period for Selle Italia or other brands. Usually if you find the saddle works for you they will apply the demo fee towards the cost for the saddle. Good luck, welcome, and have fun!

As for me, I always preferred a hydration pack over a water bottle but that was me.
