I have some VO Grand Cru Rando bars on my Voyageur. I'll measure them tonight. I have the 46mm version. They're available in 42, 44, 46 and 48cm versions. I'll bet the 48cm version will get you close to 42cm at the hoods if you're wanting to use a randonneur bend bar. I've grown to really like them.

I think the VO bar shape is closer to the Nitto B132a than the B135, though the ends sweep back further than the B132a.


B135 45cm



B132a 44cm





B177 44cm
