Don't do it. It's guaranteed that: * after hitting a couple rocks your saddle will point up in the air - poking you in the bum. * a peddle will strip from the crank arm and fall out. * Some bolt will come loose and the brake lever will swing into your front wheel sending you over the handle bars. Nothing sucks more than having to hike 7km back to your car with a broken bike. If you drove with your friends - then you'll end up waiting for them while they enjoy their ride on their decent bikes.
