They are still running monster on their kit and clothing during interviews so I would say that its safe to say monster are still in the picture. Maybe monster was not supporting the event, The race was run by specialized and if the whole monster specialized team was not at the race, then I would suspect troy and sam were been looked after primarily by specialized world team not their own personal team. Meaning that they raced under another team name, they were still representing specialized but becasue the monster team was not directly at the race specialized took credit for the other work they put in???
Been a specific Specialized run event potentially they were racing for specialized only and it was a requirement with Specialized only, hence they are still sponsored riders but they were not under the full team.
Of course I may be off base and there could be a simple explanation.
