DavidB said he does not reccomend the edge 2k pads yet as they seemed to vibrate a liitle more than normal...he is working on a new counter weight so it will decrease the vibration
this is from DavidB on his site....
I spent a lot of time testing the Edge 2000 system with the UDM prototype machines. On this machine, the vibration is about the same I experienced using a 3.5" adapter and a 4" spot pad. This was acceptable. HOWEVER, I have since gone back and tested Edge 2000 with our production machine, and the vibration is excessive.
So, I DO NOT RECOMMEND the UDM 1000 for Edge 2000 users until I have a properly balanced counterweight.
Hope this helps......I am sure it will not be long till he resolves it...
