I rode mine with 33mm 'cross tires most of the time. Did a few gravel races on it with 30mm Challenge Tubulars and even some CX with it. I also raced it at a few road stage races. The question really is what shouldn't you do with it? I wish I still had mine.This is the "limited edition" 2015 model. Will post pics later.
My first thought is to put on a set of Panaracer Gravel Kings (28 wide) that I've lying around and make this a "lite" gravel.
