More on the Kojak Rear Wheelset

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.

  1. Any noticeable decrease in speed?

    1. When I'm riding it doesn't feel slower. My ride log (yes I keep track of my stats, I can't help) backs me up. My average mph on my regular routes has barely changed. Same with my max speeds on regular downhill runs, no noticeable change. It's not what I expected. But add Kojaks on the front rims and everything suffers. So I keep the 23/402 Ultremos up front and all is good in trikeland.

  2. Hi there. If I'm reading correctly, did you mount a 23mm Ultremo to your XR 331 build at some point? If so, how difficult was it to mount?

    1. Matt, I have two complete wheel sets. The 23mm Ultremo is mounted on the American Classic Aero wheel. I edited the post to make it a little more clear. Thanks for he comment.
