My KM is the smoothest, comfiest bike I own. It’s a 2015 model with a straight steerer and no braze-ons on the fork.
Obviously if your riding rocky paths in the peaks the ridged fork is punishing (can just put a suspension fork on it though), but for singletrack, trail centres, fire paths and a bit of road, it’s awesome. Fun, fast, fairly light and very strong.
We did a 100km ride that took in all of the above, and the KM was brilliant. I’ll not be parting with mine, ever. 🙂
