I have a 2018 Lynskey Cooper CX that I bought new, have roughly 3000 miles on it. Zero problems with the bike after some minor derailleur adjustments upon delivery. The frame is plenty strong. Welds are magnificent, stack-of-dimes everywhere. My riding weight is right around 200 lbs and I take this thing over all types of terrain save for super rocky single-track. I once hit a pothole at 20 mph going down a grade and it caused a "snake bite" pinch flat on both front and rear. Really hard bottoming out. Frame and fork were perfectly fine. Mine has the Lynskey ProGravel carbon fiber fork.
