EXCELLENT info from both of you (GrizzledBastard and DorkDisk)....much appreciated!

I watched some videos tonight on the Praxis, and I agree it is a nice unit - interesting that the NDS is stepped down 2mm.

One thing is for sure - one of these cranksets is going to be installed on my bike soon...im headed to one of my LBS' this week to inquire and purchase. Upgrade fever! :-)
