@lawman91 – thanks for Your info. Very encouraging. I have one more question: have You done a proper gravel ridding on this bike? How well does it cope with rough roads?

I am looking for a fast bike with rather short chainstay that will also be comfortable on the gravel roads (at least 35c tire). Genesis Datum is on my short list among with Kona RoadHouse and Specialized Diverge Smartweld. Datum is the most tempting choice but also the most expensive so I have to be sure that it is really a best choice :)

@lawman91 – Do You think that Datum frameset has enouth clearance for 35c tire like tubeless Schwalbe G-one 35c? I know that Datum has 33c tire as standard but I think that the real width of these tires are much lower and real 35 mm tire like G-one may be to much. Or is it?
