[QUOTE="JL"] Knee damage from a low side ? How did you end up on your face ? More usual to get that on a high side. And yeah what you're sliding on makes a big difference - knees are pointy and hence more likely to wear through [/QUOTE] I low sided on Lake Mountain when I hit some gravel that I didn't see. Very very quick... corner *wham* bike went out from under me and I was left in the air like a cartoon character... I landed on chest, hands and knees... hard enough on the knees to rip the top layer of leather reinforcing off my leather pants so it can happen. G-S
