far from real common. i dont know anyone with a damaged bulkhead. you would think at least one of them would have failed in the hundreds of g4s ive dealt with. how about my friends rental company that sends 10 sleds out on the daily to be ridden like a rental. regular rigors of riding does not include smashing rocks sorry
At least Poo got the design right and the a arms fail first, not the bulk head.
Not saying hits wont cause failure, just doo got it wrong on what fails.
We are clearly never going to agee........just find it amazing how you have not seen a failure and there are so many.
