@xavierdisley possibly... I hadn't really given much thought to Crr and just used a 'typical' value I saw on TTF. For this year I was sort of working on the premise that consistency in the data was marginally more important than outright accuracy as my main goal will be to improve my position. I'm not really in a position where I can do detailed testing of different wheel combos etc.
This weekend I was planning on trying 3x 20 minutes using my TTbike with training wheels (with magnet) to get some updated baseline numbers. Runs 1 and 3 I was going to use my normal position and then use run 2 to try something different. My first thought was simply to ride run 2 sat up on the base bars in an attempt to see weather my testing protocol was sufficiently sensitive to detect a big difference, but maybe I'll just try keeping my head down more instead.
Keep your head down for the second (obviously with aero helmet on for all of it). It's good to know whether tucking in makes you quicker and you don't have to wrench on the bike in between intervals to test it.
