All I can say is... wow, the Gravity Dropper just rocks on an AM rig. Yesterday, we drove to Polson and visited the GD factory. Both me and my buddy ended up getting the new 5.5 GD. It drops 5" and you can stop it 1/2 way down for techy climbing. After the bikes were all hooked up the owner of GD, Wayne, asked us to go for a ride. We ended up doing a 10 mile ride right by the factory. The trail was up and down and I used the GD 20-30 times. It performed awesome and never one glitch. How did I ever live without this thing? The GD and the HammerSchmidt make my AM rig more fun to rip. The up and down trails are just so much easier to flow. If you dont have a GD on your AM rig you are really missing out. I highly reccommend it! Wayne and his crew are top notch guys and Wayne can really rip.
