    There's a summary and an even shorter summary in the next post if you don't feel like reading a bunch of half-math and geek speak.

    I was reading this enormous thread on bent raptor frames and found some really interesting talk about hitting bump jumps versus ramped jumps. A steep bump will wreck your truck harder than a smooth launch several feet in the air (of course a bad landing...)

    SUMMARY


    TL;DR: Height of the bump relative to your up travel is extremely critical. The faster you hit a bump at the less time your springs have to push the truck up and away from the axle trying to smash into it. A gradual rise into a jump gives your suspension time to cycle smoothly and change the trucks overall momentum so it's going up and off the ramp, instead of forward with the wheels struggling to rise fast enough to keep up. And coming off a jump you get the full length of suspension travel to soak up the landing. So if you see any sudden rise in terrain that's bigger than your up travel SLOW THE FUCK DOWN.

    Another explanation on why a smooth jump is safer than a hard bump.



    edit: haha I got to page 24 in that thread and someone FINALLY brought up the point that those hard kickers should have been marked from the prerunning. Why would you go 50+ down a stretch of road you've never hit before?
