The Slate was replaced by the Topstone Lefty:

So allow me to correct the record, as it were:
Niner MCR - Discontinued.
Cannondale Slate - Discontinued and replaced with updated, upmarket version of the same form factor with 700c wheels and rear suspension.
Specialized Diverge STR- full steam ahead, apparently getting another update for MY2026.
Lauf Siegla - Highly recommended for racing and riding, the Lauf suspension fork is perhaps the most aerodynamic forks available for gravel.
Trek Checkout - Not even released, will be entering a very different market than the Niner MCR.
So great, we got 1 bike discontinued and 4 going strong. Great work.
Don't forget:
BMC URS
Canyon + DT Swiss Grizl/Grail
Giant Revolt X
Etc.etc.etc.
There are more gravel bikes available with stock suspension, today, than anytime in the past. Suspension for gravel isn't going anywhere anytime soon, we're more than a decade into it and it's only gotten more common and better as time has passed.
