I think you guys are probably right. My computer crapped as soon as I came out of transition so I had no idea how fast I was going the whole race (and OF COURSE I get home and it works fine... UGH!). Usually during a race I do pay attention to my MPH and a pick it up a bit if its low. Also as I said this course was a lot of long smooth roads and lot of high speed sections, so those wheels may well have given him more of an advantage as well. Neither of us have tri bikes, we are both using road bikes with aero bars. I definitely have better tires (Conti GP4000s vs his Specialized Mondo sports). I did feel the advantage with my wheelbuilder disc that was for sure as I was able to really drop people in the downhills that I was just basically slowly gaining on.

We have 2 more events that we are definitely doing this year, one has a lot of climbs which I have an advantage over him usually, and the other is partially a longer flatter course which we may see the same advantage for him. Here is me, not the perfect position but it works for me.
