I'm loving all of the responses.. I'm more so looking to buy an upgrade to what I currently have with higher end components. I don't get sick of bikes quickly so If I get this titanium or steel frame bike.. It will be my main go to forever or unless they severely update components on a level that they significantly improve shifting & ride and can't adapt to my frame.. then sure maybe then.

The reason for choosing a gravel ride as opposed to just road is I do like to go on dirt trails and would like versatility with tire width choices.
I really love the 2X set ups I see with Gravel bikes. A decent big cog for fast road riding and gearing suitable for rougher terrain & hills.

The only other bikes I could see myself considering as an addition to my Toughroad & Titanium build would be like an Ebike or full on MTB.

I don't buy into the magic carpet ride of titanium but believe they & steel both have a nice ride on a quality frame mixed with a solid set of wheels & tires etc.

I'll look into the other manufacturers you guys listed here.
