Man, that sucks! I’ve only been riding MTB’s for about 8 months and have only had one crash that was "sorta" bad. Endo at only 10 or 12 mph. Landed on my head and shoulder, knocked the breath out of me and damaged my pride mainly. Everyone keeps saying, "slow down old man" when I do the downhill sections but I love that $*&%! I WISH I was 45!!
