This one is nearly all Columbus Zona. This rider will be checking out the Santa Monica mountain roads and trails on this frame. It will be paired with an Enve G-series fork and most likely will have Shimano GRX components.
This frame is a bit of a milestone for me- frame # 100 and the 37th steel CX or gravel frame of the year. I think that might be the largest annual total for frames like this for me, over 1/3 of all the frames I built during the year.
This one has ample tire room, enough for a 2.2" tire so this one is almost a "Drop bar mountain bike " .
