After having a 2004 rt1000 and selling it for fit reason( Im the blind stoker, taller than my wife) and getting a 2007 Trek T2000, I now just bought a 2010 RT2 Cdale.

Simple, more room in the rear than the 2004, and wayyy stiffer than the Trek, and never hooked on the T2000, did not match the road feel of the old 2004 RT1000.

So, upgrades on the new cdale are a wound up duo disc fork, flight deck, new wheels for the look I must admit, but turns out they are lighter, almost as lights as the T2000 race lite wheels.
WI Black 36h disc hubs
Black spokes
White non machined side wall Deep V rims
I wanted to match the white frame.

-12-25 cassette, I hate the wide ratio on the stock casettes

Did not however try the new parts, its winter here so will know next year

Its still heavier than the T2000 but its worth it for the stiffness and better brakes (ok, and for the look too! )
