    Stripped Lefty / ForkUp adaptor -- advice needed

    I have a Hurricane Components Forkup adaptor mounted to a Lefty Max -- and unfortunately the Forkup is not coming off. :-(

    The mounting bolt, or the female threads in the axle, feel stripped -- the pattern is ~one rotation CCW with moderate resistance, then an increase in resistance, then repeat.... I understand the threads in the Lefty are helicoil, so perhaps another possibility besides stripped threads is the helicoil is detached?

    The forkup is on tight... no wiggle.

    Recommendations on how to proceed? Carefully drill out the bolt? Other ideas?

    This is my wife's bike. Neither of us can remember who last mounted the Forkup (good thing, that!) but I wanna fix this as quickly as possible....

    A good shop should be able to clean and replace the threads.
