Today I was riding my bike and was messing around with the headset and spacers to adjust the height of my bike.
After, I tried every combo and decided to stick with the old configuration.
But problems start to show as when I try to "skid" at a fast speed, when I push the pedals back I would get this "empty feeling" as if my crankset is going backwards WITHOUT engaging chains!
The pedals would not engage the chain thus the rear tires are not moving backward, feels like only the crankset is moving backward.
This had happend twice today and I really dont know what is wrong with my bike.
I doubt the problem have anything to do with headset but what then?
This is a picture of my bike, I just bought it not long ago...
Thank you for helping me nub
