Re: [ST] for Marc -



I got a good one.. 
   
  Last weekend, while hiking at 2 am, kinda tipsy from the scotch enjoyed by the camp fire, I ended having a bit of a fall. I ended up walking of a small cliff, about 15-20 ft drop. Luckily, it was dirt at the bottom, and a few branches slowed my impact a bit. I ended up with some of the worst bruising I've ever had, limited mobility in my shoulder, which is still sore, and being the brunt of the jokes the next night. 
  Last August, at a speed around 60 mph, I crashed my ST into a car head on, thanks to some mid corner gravel out of sight due to trees. With the last second high side, I deflected over the pass. side of the car (it was a right hand turn) grazing the pass A-pillar and windshield. I landed in the woods, and a foot from a tree. I suspect the deflection slowed me down once again, and I just sustained a slight fracture of my wrist, and bruising up my thigh/side. 
  Now I wasn't in my PPG during my hike, but I suspect that the verticle drop was worst than the foward motion impact. So, that said, sliders are better in crashes at speed?

Your analogy is tragically flawed...

regardless of the forward motion, on object will accelerate towards the
ground at the same rate under the pull of gravity (unless it has wings or
something something creating lift from a forward motion...). So the force
when hitting the ground will be identical whether moving forward or not.
Your analogy ends up with two very different impact speeds (falling from
standing and falling from your roof do not have the same acceleration
distances - the object falling from the roof will have more distance to
accelerate and thus be moving faster (normal to the ground) and thus have
a greater normal force impact with the ground. To make the analogy you
need to be running and fall to the ground, or just standing and fall to
the ground. In that case, the impact is the same.

>>> I've been told by more than one person that sliders can do more harm 
>>> than good in a big off. <<<

Actually, the worst damage done by frame sliders is usually in a tip
over of a stationary bike, due to the angle of the impact and the full
weight of the bike landing on the slider. The greater the speed, the more
of a glancing blow the slider receives. To demonstrate this for yourself,
don your protective gear and run as fast as you can through the house and
out the front door, jumping over the steps, landing on the sidewalk and
sliding to a stop. Note the sensations, including pain, you experience.
Now climb up on your roof and jump off, falling straight down to the
pavement. Feel the difference?
