Both bikes are considered entry-level and the same price with full or mixed 105 components, exposed front brakes, and wheels/other parts that will probably need to be replaced down the line. Cervelo has a proven history of excellent aerodynamics and probably a bit easier to work on. BMC has rear storage but difficult to wrench due to the rear brake, which can also make wheel and brake pad swaps difficult. Both owner's threads are filled with happy owners as well.
Is there anything else I'm missing that separates the two other than the Cervelo's ease of wrenching (and better aerodynamics) and the BMC's rear storage? Would the aerodynamic advantage change by adding some type of aftermarket storage to the Cervelo vs the integrated BMC storage? I tried searching but no results seem to compare the redesigned BMCs that have rear storage.
