Recently I posted about the new wheel setup for my Catrike 700 "Black", Catrike 700 Sweet Spot. I've taken a few more rides since that post on March 27th. I'm not sure how much I'll be using the old American Classic Aero with the 23/622 Ultremo. The Kojak/DT Swiss wheelset makes for a sweet ride. It seems that the key to maintaining a fast and nimble ride is keeping the 23/406s on the front while smoothing out the rode a bit with the 35/622 Kojak on the rear.
Bottom line...if I want to squeeze every ounce of speed and acceleration out of the 700 then I use the 23mm Ultremo mounted on the American Classic Aero wheel. For the slight bit of speed loss (not often noticed) and considerably more comfort then going with the 23/406s on the front and the 35/622 Kojak on the rear is the answer.
Note: The DT Swiss XR 331 rim is considered a MTB rim. It has a 20mm inner rim width (see DT Swiss tire chart). I went with the more robust rim for peace of mind when charging down rough roads.
