Racing with the W3/4 on my new Orbea Ordu - set up with the Zipp Sub 9 and HED 3c. If it's windy (likely to be the case), I will swap the disc with my Easton Tempest tubular. I'm just not that used to the bike and the disc yet. I am first one out in my group and there is a 2 minute gap between the W 3/4 and the W Pro/1/2 - so I won't be passing anyone! Goal: don't get passed.
