As others have said, maybe because they actually think its going to make the difference in winning races and competing? Free shifting, weight distribution, unsprung mass. If one of these teams wins, it doesn't just get them 100k, it buys the team/brand credibility. If gearbox bikes come out of this year with a 2 wins and a few podiums, your not interested? Crazy how much skepticism something new and progressive is getting.
