I have used the Dyad (mine are the Aeroheat which is the original name used) rims for many years without issues for weekend bevets and commuting. I also have a newly built set of Cliffhangers for my other touring bike. Both wheel sets are 36 hole. I selected the Cliffhangers for this other bike based on my experience working in a shop for the past 40 years and putting them on a lot of mountain bikes. They are heavy, but tough as nails and I will be using them on a tour out west that will encounter a lot of unpaved roads.
