Yesterday I understood it’s not good to wipe out, get ejected and land on
your seat : result, the back section (miyata) was neatly broken along with
the plastic frame and the bumper. I was wondering if there is something to
do to keep the seat functional (no trials or hard jumps, just quiet
riding) ? glue ? I guess is out of question
