I have a set of 20f/24r King R45 hubs that I was originally going to lace into a deep rim for triathlons. Might still do that, but I am wondering about how they would do with a set of carbon rims for cross? My tri days are limited due to injuries/back problems and I have these sweet hubs that need to be built up. I think that they are probably not "enough" for cross racing and that I would be better off getting a 24f/28r hubset for cross at my weight (185lbs). Thoughts from the cross racers?
