Yes, I love the traditional classic Randonneur bend bars with their narrow shoulders, notable upward rise from the center, shallow drop and wide flare at the bottoms. I have several different ones, from several companies and various different nationalities. To be honest, they are my favorite style handlebar... period. Each to his own taste. If I see a bike with Randonneur bars, I would expect that I will feel quite comfortable riding it.

But, I will say that with their narrow shoulders, I would think these are not something you would want for a racing bike. They would also simply feel very unfamiliar to you if you are used to either the classic Cinelli bends or else any wide modern anatomical bend road bars. And, I also think they would definitely feel very odd if using STI/ERGO brake/shift levers, but I may be mistaken about this [I haven't tried it, yet].

Nitto 135... I think the Japanese had long ago distilled the essentials of the style and all the others I've seen amd which I own have elements very evident in this model - distict bottom flare, and narrowed corners, shallow drop. For these purposes I would lump most any of the specific vintage randonneur bars I own together with these since they are in current production and are certainly the most commonly available. They are beautifully finished and I would always feel comfortable riding on these.

Rivendell/Nitto Noodle #177 This is very different as you can see in the photo posted by Mariner Fan. These have wider corners and tops which are drawn back rather than upward from the center. Very little flare at the bottom. These would probably be best for anyone converting and retaining STI/ERGO levers, and these maintain a similar quite vertical orientation for those levers. I ride in the drops a lot, and I find these much less appealing for my riding than almost any other handlebars on the market. If [as perhaps only myself and the late Marco Pantani] you happen to climb in the drops, you would NOT like these at all! The corners, whenever I ride in the drops, are forever hitting against my forearms. This is odd since I tend to mount my handlebars higher than anyone else I know - close to level with the top of a saddle as possible. But this problem is increased because of the exaggerated backward bend of the top the wide corners and the lack of flare at bottom.

Many people obviously DO seem to like these, and they are available in more familiarly modern very wide widths. But, I'll offer a minority position here and state that I find them simply very uncomfortable. The corners actually slope downward from the center a bit at the corners which to me would even seem to be counter-productive to the stated intention of having the effect of "raising" the resting position when riding with hands at the tops of the bars by drawing them farther back (rather than up). Personally, I even seem to feel my hands sliding downward and outward in that position with any of my weight at all shifted forward. So, maybe these were intended for bikes with a short forward reach (or riders with long arms) and best for somehow "resting" in a very vertical position with your weight mainly on the saddle. I'd rather just use a NITTO B-114 or B-115 "Classic" model among any of the more conventional looking retro-styled bars.

The Velo-Orange Modolo bars look interesting. Modolo had always come up with very unique designs. I'd be very interested to hear someone's analysis of these from actual use on the road. They seem as if they might actually offer some of the advantages of a European "TREKKING" handlebar [or "butterfly" bar] but I can't quite figure them out. The wide flat top section certainly looks inviting.

Traditional Randonneur bars will look either beautiful to you... or simply very weird. They definitely stand out when you see an approaching bike with them mounted. Sure, this bike may just look like any low-end Schwinn from the 1960s, but I very much like that look, anyway.
