"monstercross" bikes are rigid fork.
i've seen only a couple "carbon suspension forks" EVER... two Super-high dollar Lefty Cannondales... they were MTBs.

As to the issue the OP is having.. i'd be looking at the Dropouts REAL CLOSE, and also the triple clamp/tube junctions...

there's a strong chance that the Quick Release is bottoming out on the axle before the thing can clamp solidly, too......

OR The AXLE IS BROKEN.

Carbon tubes fitted into aluminum Triple clamp and dropouts, right? Brand? Model?
