I’m looking at swapping out my current handlebar and stem (42cm, 110mm) and looking to switch to an integrated aerobar/stem combo. I’ve got an Emonda and the new Bontrager Aeolus RSL VR-C that is coming on the new Emonda looks like a great option.
It would also help me clean things up on my bike as I have a Di2 junction box sitting under my stem at the moment.
Given the move to an aero bar, I was thinking of also going slightly narrower than the 42cm I’m currently using, perhaps down to 40cm. Would that necessitate any adjustment in stem length or should the small difference in width not have that great an impact?
