Was this just a freak thing likely to never happen again? crap happens on the trail

Was I going to fast? Probably were going to fast its always the rock you dont see that gets you

Did I air down too much? Nope 22psi is fine

Was that the recommended repair? Hammer it in place have rim balanced again

Should I replace the rim or is it all good if it continues to hold air? its good

Are all repairs on the trail just a question of if you have a big enough hammer? 90% of the time this is the case
