I have used Nitto Moustache Bars for about ten years on my around town bikes - A Moulton Stowaway and a LeJuene Track Bike. When climbing standing up, the position has felt awkward and much less efficient from the first use years ago and continued to this day. The placement and use of brake levers also feels unusual and a little awkward. Other than these concerns I have been happy with the M Bars but have not chosen to use them for touring as I prefer off pavement routes where braking and shifting at the same time appears difficult.
