32 hole road wheels will be fine if you take it easy.
I use a Trek 1200 for commutes and occasional road ride when my training bike needs a tinker.
I weighed 98kg (88kg now) took it through our local trails on a short cut-not my idea. The leader forgot we were on roadbikes and not mtb bikes…
If the road is bad just take it slowly. Even some training routes have the odd really bad road so you just take easy over that and the rest of the time it's smooth.
For winter I'd rather a cx bike for larger tyre width and better brakes.
The best deal will be on roadbikes as they sell more than cx (which is slowly catching up)
Also place a wtd ad in classifieds. I know one seliing a Genesis CX bike but he wants at least £450 for it.
Shop around and haggle?
