well, when i started front touching up i totally miss judged my tap and ended up leaving my nads on the stem which resulted in a very painfull 10 minutes on the deck and a hairline crack in my stem. however the following day i went riding again with the stem still fitted what an idiot i know, i did a 7 foot drop, the stem snapped ripped my brake hosing off and i wiped out backwards slamming my head on the floor knocking me out cold haha
