40k out and back time trial tomorrow. Wind will most likely be 10-15mph coming from the 1 o'clock direction for the first 10k and then a right cross for 10k a left cross for 10k and from the 7 o'clock position on the way back.
I'm going to run a 404 on front and I am committed to running my PT wheel on the back. The question is should I run it without the disc covers (it is an Open Pro) or with the disc covers. I'm 195# so the wind does not bother me quite as much as lighter riders, but would the energy fighting the cross-wind for 20k cost me more than the aerodynamic advantage of running it as a disc?
Thanks for your help.
