Actually there is no need for it due to high-volume tires that usually come with CC bikes. By the looks of his bike those are at least 700*32.

I have a full aluminium CC bike, and was sure that CF fork will be the first upgrade. Now, after three months and about 1000 miles later I see no point with 700*32 tires, and less than 6 bar in them. I ride road, gravel and single track (60/30/10%).
