I think Hed and Zipp both offer a Clydesdale build and I'm sure others do as well. Certainly on the pricier end of the wheel spectrum, but so is breaking an $800 wheel I suppose. FWIW, I've heard over and over that the Hed 3 is pretty much bomb proof.
i started out at 215 and am currently 195 but i still ride the HED JET 60 stallions. They are bombproof and great for training and racing. THE ONLY WHEELS YOU WILL NEED!
