I rode my bike for months before and never learned to skid.. I was off my bike for a while and took it out today now that I have read how properly skid and I started getting it imediately. The issue i am having though is a couple times when I locked my leg and lift my front pedal it felt like my cranks were moving and the wheel wasnt. It actually felt like I stripped the spindle and the crank arm was moving around it. But when I got home and checked everything, the cranks were straight and tightened, my cog seemed to be tightened fine. I dont know what's wrong and couldnt figure it out by investigating myself. I then started to think that maybe this was just the feeling when the wheel goes a bit backwards perhaps? Anyone have any clue what I'm talking about or experienced the same thing?
