My money’s on Ritchey Evocurve bars. They’re stiff enough to be confident decending, but just enough flex to take the sting out of the road on the hoods/drops, and the drops seem well sized to give enough room for big hands but still have clerance for wrists. There’s not a huge number of bits I’d buy again without reservation but they’re on the list, light too, especialy with the matching 260 stem.
I dont bolt lead weights on it for a start, like most of the “pro peleton” has to! It really isnt difficult to build a bike below 7kg.
Agreed, my CAAD4 is 7.3kg, and that’s been built on the cheep!
Speccing/choosing wheels and Clicking “buy” is easy of course.
It may also be cheap or good value.
The wheels may be durable with readily available spares
Achieving all 3 may not be easy!
The wheels on that bike are 1275g (without QR’s), the spokes are conventional J-bend’s, the rims are Stans, the hubs are cartrige bearings (and so far, reliable), they’re also stiff enough not to rub, comfortable, wide, slightly aero, what more could you ask for? And they cost <£300.
