BMX used to have wayyyyy less Nationals and way more teams. Having run two factory teams its near impossible to field a team. Say you make just 75% of all ABA and NBL races thats like 100 nationals. entry fees alone would be 1.3 million dollars and add hotels and food and your like at 1 trillion. Untill a sanction steps back and runs less nationals or a new sanction is started that features less races its not gonna change.
Also what real incentives are the ABA and NBL giving to teams? Riders can do their share by only buying bikes from compnies that sponsor teams, thats one of the reasons I have a Redline.
