That’s quite some feat. I recently commented in another thread that I have not done an endo for at least 6 or 7 years. Likely 10. My daughter hasn’t done one since getting into biking in 2015. I was chalking it up to 29 inch wheels and modern geo.
Best wishes for a speedy recovery!
PS - my daughter and I both have a Bell Super 2. Neither of us have used the chin bar even once. We bought them with the best of intentions. I worry about my daughter because I have a crap load of money sunk into her teeth. At least a half a bike’s worth. Lol!
