I have two mustache bars on bikes. One on a 70's vintage Motobecane Grand Touring, and another on a Nashbar road Fra-may I built over the past few years. I love them in terms of versatility and comfort. Most people with drops do not ride them on on the drop part. I did when I was 30 years younger, more flexible, and without some old geezer arthritis. However, as I got older, I found I was using mostly the tops. A friend turned me onto MB. They give more hand positions, one can get aero, and they give you the option of being more upright for either urban riding or comfort. I have done centuries with them without problems. The secret to setting them up is to have the MB higher then the saddle, and use a shorter stem. Rivendell web site will explane more. I have used the dirt drop stem on both bikes with great success, since it does get the bars up with a shorter stem. My Moto have downtube shifter, and my NB has bar end shifters. I highly advise using the barends due to comfort and ease of reach. One thing you will find among those who have tried mustache bars, they either love them or hate them.. There never seems to be a middle ground. Another thing about these bars is that they are quite the conservation piece. I rode a century last year, and I was the only one with these bars. I got so many questions about them, with people either thinking I was totally nuts, or the bars were "real cool". I bet on a LHT they would be great. If I ever build up a LHT, mustache bars would be my first choice.
