What’s wrong with your current frame?
Too heavy? Not enough mud clearance or just a bit old and you want something new and shiny?
If you just want a new frame the easiest option is a new akrose with new updated features and geometry etc. The akrose is highly rated on stw.
If you want better tyre clearance or a lighter frame then look at different gravel bikes. 2nd hand frames or try planet x, ribble or merlin for the cheaper frames.
If you go for wider tyres you might need new rims?
The other option is sell your current bike and just buy the bike you want.
My “gravel bike” is a rigid 29er with flat bars. I just change the wheels and tyres from 29er plus tyres to 2.3s to cx or slicks. It does everything I need. It’s comfier off road but slower on road.
