My analysis of the Domane wheelset for touring is: they're not great.

The main issue is low spoke count. All other factors being equal, low spoke count wheels are always going to be weaker than higher spoke count wheels. It is possible to make a low spoke count wheel much stronger by 1) increasing rim height and 2) using butted spokes.

Which brings us to the secondary issues.

1) the rim doesn't seem to be particularly high profile. The rim is probably not stiff enough to properly counter the low spoke count, which will make the wheel inherently weak.

2) the spokes are straight gauge. Double (or triple) butted spokes (ie. thinner in the middle) are stronger than straight gauge spokes which have a constant cross section along the length of the spoke. The added strength of thinned spokes is counter intuitive, but thinner spokes stretch more, which give the wheel resiliency against loading. Even a high spoke count wheel can fail surprisingly easily if it is built with straight gauge spokes.

But in the end no one can say whether the Domane stock wheels will be ok or not. Personally I wouldn't trust them though.
