Lot of people workin on jumps…
@Lowey – without wantin to be too pushy, check out the courses we have on jumps, pumps and drops at http://www.cycleactive.co.uk or get a private day of tuition if you prefer.
@tron – great! I wrote that article so I'm glad it worked for you.
About pullin up, or pushing "down". Neither is the answer. Think about having a bouncy ball and droppin it onto a ramp – it bounces off forwards. Now push it hard down onto the ramp – it bounces further. reverse that process and that's what your tyre does – push it into the face of the ramp and the harder you push, the higher you go. Pump=Push but it's a short, snappy push.
As for pushin down, if you do that a lot of your energy is soaked up by the forks, especially if they're 5 inches plus and well damped. So you push forwards and just a bit down so the energy is instantly turned into lift.
Goin off drops is similar. This time you definitely push forwards and down into the ground, and the instant, smooth rebound from the tyre (not the forks) gives your lift.
@younggeoff – As for the bike choice thing, you definitely get more height and quicker response from a hardtail because much less of the pump from both hands and feet gets absorbed by the bike. However, the flip side of this is that it responds much more quickly, so is maybe a bit harder to control than a full sus bike.
But you can perfect the technique on any bike…especially with a good coach….check out the courses run for us by Rich Barnard, Jon Chalmers and James Richards at http://www.cycleactive.co.uk We cover Cannock, the Lakes, Malvern and Ae Forest.
