I Just recently had my suspension done by Dale EO Engineering and let me tell you WOW what a difference. He changed the springs to match my heftiness and also did a revalve. I ride a 2010 FE570, I am 235lbs and before I had this done the bike handled decently but there were two major problems 1) if I hit the whoops with any kind of speed the back end would really start to kick & swap, not good, 2) the front end would deflect when in the rocks especially on a rocky uphill but now both of those issues have gone away. The bike handles WAY better than before. Now I feel real comfortable hitting the whoops with speed and I am not worried about the rear kicking around and ejecting me off the bike :shock: , the front end works great in the whoops and is also soft enough in the rocks to where it just soaks them up. Cornering is also better because the bike is staying up more in the stroke and not squating as bad as it did before and on uphills & downhills the bike handles way better also because it is staying up more in the stroke. I loved this bike before but now it is just that much more fun to ride. So, if you are interested in getting your suspension done I would definately check into having him do it, he put together a very detailed spec sheet of rider info and of the work he did, he does it right and guarantees his work and for a reasonable price too! Thanks Dale!
