So I'm new to CX, trying to learn/practice as much as a I can. Recently did my 1st race and there was a certain turn in the course that a few times I felt my front wheel wanting to slide from under me.

I didn't fall, but I could feel it jerk and wanting to slip and I would try to correct right away. Is there something that I was doing that would cause that? Too much speed? not cornering properly? Just trying to figure out afterwards what I need to do better.

btw running Michelin Muds, 38psi front, 40psi rear, weight 168

thanks
