I have an upcoming 12 hour time trial. The race is on a fairly brutal course with over 10,000 feet of climbing in the first 110 miles. The roads are also pretty sketchy in places, lots rough chip seal pavement, cattle guards, expansion cracks, etc.
In the past, I have run zipp 404's with 23mm pro3race tires & latex tubes and I've taken a pretty good beating. I pre rode the course recently and there are couple sections where I was getting finger numbness just from road buzz. (and that was on my Cervelo RS, which is pretty plush)
I have the option of running zipp 101's or zipp 404s. I've never tried tires wider than 23's but I'm wondering if I should put a 25 on the back or even use two 25's.
What do you guys think the optimum combination of wheels & tires will be to put an emphasis on comfort but not sacrifice excessive speed?
FWIW - I'm about 170lbs and typically run about 115 for tire pressure on my p3race tires.
