Pedal stripped righ crank arm. 2017 Haibike Xduro Trekking 4.0

[Jens5]

As title states. Coming back fro a 20 mile ride, felt something loose. Right crank arm, pedal insert stripped. Put a pedal wrench on it and threads on the arm gone. Definitely stripped. Pedal are Race Face "Chester's. Need advice. Find a new crank arm? Some kind of repair or different crank arms entirely?

I see arms listed on Amazon; you could get Race Face arms if you so desired. Some shops can repair your existing arm by installing a insert.
