After having used HED Jets for several years on my tri bike, I am getting a set of RSL's (75/62).
Looking online, seems to be some mixed recommendations on tire width (tubeless). Seems like trek leans towards 25 for aero, but I had read an article on slowtwitch where the reviewer said he had a very hard time getting 25's to bead up, and felt the wheels were more suited to 28's.

What say you all?? :)

Nominal 25s (like 28mm WAM) will be ever slightly faster in a wind tunnel test, but there's more to going fast than wind tunnel results. I would just run 28s.

Thx, that is what I am leaning towards (28). :)

Now the horrible task of deciding on a tire!!
