Some gravel bikes are built to explore.
This one looks like it wants to start a fight. 🏁
A Specialized Crux built around one idea. Keep it fast, keep it clean, and don’t follow the usual spec sheet.
Up front, Shimano GRX RX827 Di2 controls the show. Out back? An XTR M9250 Di2 rear derailleur, bringing MTB-range capability into one seriously quick gravel package.
Specifications:
Frameset: Specialized Crux
Wheelset: Specialized Roval Terra Aero CL
Shifter Lever: Shimano GRX RX827 Di2
Rear Derailleur: Shimano XTR M9250 Di2
Handlebar: Zipp Service Course XPLR
Stem: B-TWIN
Crankset: Elilee XXE X310
Pedals: Favero Assioma RS

The result is the kind of Crux that looks completely at home on gravel…
until the road turns smooth and everyone suddenly starts suffering.
