hi could you do a video of how to gap to front because im fine with gapping and rolling gaps it just i don't get the leaning forward movement in the air at all it would be a big help
Well "20" inch is usually better to to start out on but not always the case is you come from a motorcycle background of mtb because your more used to it with balance etc.
If your looking for a mod [20 inch] make sure it has a 19 inch back wheel because if its 20 and you want to upgrade to a 19 inch back wheel you where the brake mounts are the brake would not be near the rim
