Carbon GT potential engine problem after offroad riding

Hi everyone!
Today I had my first long ride and I did almost 20 km with the A/T set most of them offroad. Now it seems that the engines are not spinning freely or at least are not spinning as before.
I have taken the wheels out and the bearings look and work smoothly
Any suggestion will be highly appreciated! I'm worried!

Thank you!

 

Thank you Zerofuhks but I did it. Everything seems to be fine, I don't know maybe it's just an impression. Tomorrow I will try the board to check out if it's going slower or not
