I’m looking for fenders/mudguards for a trend-appropriate, fat tired gravel bike (Lauf Seigla with RaceKing 2.25s.) Tricky as most gravel-specific fenders are too narrow, and many MTB options offer limited coverage or or designed for use with a suspension fork.
I’ve had some success with an SKS X-blade clipped to the seat post; a bit unwieldy but it works. A buddy has the WinWing and it seems comparable, though he gets a bit of spray from the area between the fender and the seat stay. X-Blade Dark Rear Quickrelease Fender – SKS USA
The front is trickier. SKS X-Board or similar downtube-mounted guard seems somewhat helpful. Not sure of other options TBH: X-Board Downtube Mount Quickrelease Fender – SKS USA
