He runs eagle wheels, district, and addict
He screwed over Alot of people, not his employees, but he took advantage of the other owners of district and addict who basically built the companies, and ran them out.
Now he's just in it to make as much money as he can off our sport by making products pulled out of the previous part owners asses
Edit: to destroy Marcel's influence, you would have to destroy all of the companies he runs. So we would have to boycott not just district, but eagle and addict too (even if it means affecting all the team riders)
