Ok competing in my first LOTAJA and not sure which wheels to use. I have a pair of Kinlin 270 rimmed wheels that come in right over 1400 grams with the rim tape. So these are a 27mm wheel. The other set weighs in around 1600 with rim tape and are a 30mm wheel. I am wondering which one would be the better choice for this race? I will be running 23c Conti GP 4000s on them. I can get up any climb but am by no means fast on them. I train solo so don't really know how to figure in the dynamics of group riding into the equation.
I also have a 38mm set of tubulars that are several hundred grams lighter but am still not comfortable with changing a flat on these so hesitant to use them.
Here is a description of the course:
Elevation gain of over 9700 feet over the first 110 miles. Then just minor upgrade with possible windy conditions to the 206 mile finish. Any insight is appreciated.
