I managed a 02:48 on my gravel bike this weekend (TREK Checkpoint). Running 40c Maxxis Rambler tyres. I did built it up with 2x Force Compact crank if I ever wanted to use it for specific road races with road tyres. But I love these wider tyres, and the super comfortable ride it offers on the road. Lots of grip, durability and disc brakes - a win win.
