Bmx has evolved a lot more than some other sports in the same time, and with that all sorts of trends and beliefs. Whats something you heard/believed/stuck with you even though it is now either outdated information, superstition, or just not valid.
Biggest for me is the “2peg rule”. Older kids around me (early 2000’s) always said only pussies used 4pegs, its ugly, and cheating. According to them, if something is on the wrong side, you either rotate or go over the rail to make it work. Its complete bs and I love watching 4peg edits, but I dont think I will ever change. 4pegs still looks ugly to me, and I like how it forces me to be creative and adapt to certain spots. It has become a big part of my stylo.
