NBD – Enjoying my new-to-me Jamis Renegade a lot

I'm coming from many years of MTB. Excited to be moving over to gravel. The choice wasn't completely out of interest… I'm hoping it'll be a little easier on my back. Years of beach volleyball and MTB have taken their toll. I need a little less impact, and maybe a little more speed.

Any recommendations for other upgrades? Suggestions? I already got a new carbon seatpost and a WTB Gravelier saddle. I'm not 100% sold on the saddle. A little on the stiffer side. I ordered a Selle Italia Sport Gel Flow, but I'm afraid that's going to be too plush.

Also looking for pedal recommendations.
