I will be facing a similar challenge as i ordered an XR4 and want the 5D in celeste. I think your shop needs to try and simulate the vision's reach, drop and stem angle with by combining bar and stem on a trainer. Most fitters would obviously prefer the flexibility of the traditional setup, but i think the bike looks better with the matching aero bar.
The same here, I also want to know the exact distance between the center of the stem until the curve of the handlebar (the reach). In a classic combo it will be for example 100mm (length of the stem) + 85mm (reach of a compact bar).
Next week, I go on holiday to Italy and will visit Milan. For sure, I will drop in the bianchi bicyle cafe http://www.bianchicafecycles.it/en
I hope to find the answer over there.
I found the following specs online, which does help a bit for measurements (particularly the REACH):
— Sizes: L100 x W400, 420, 440mm(c-c)
— L110 x W400, 420, 440mm(c-c)
— L120 x W400, 420, 440mm(c-c)
— L130 x W400, 420, 440mm(c-c)
— Compact 125mm drop
— 80mm Reach
— 2˚ outward bend
— Weight: 395g (420mm)
As for the XR4's Bottom Bracket, the specs indicate the XR4 uses PressFit 86.5x41mm. Im not too familiar with BB standards, but does that mean its essentially a BB86? (not sure what the .5 is about) If thats the case, would it be correct to buy a PressFit BB86 (standard 24mm)? Something like this:https://www.bike24.com/1.php?content=8; ... 10619%5D=1
