Just wanted to update this thread with a ride report, particularly regarding the moustache bars.

Since this makeover to new bars and Capreo gearing, I've had many long rides. Longest was 84 miles (with 4K ft climbing), with 15-20mph winds. The bottom line is that I am very happy with the transition. The moustache bars gives me wide range of hand positions which are comfortable. On the long ride, I did 42 miles into headwind, yet could sustain a low profile and still be comfortable. I have Ultegra bar-end shifters which functioned well and were easy to access from the "sit-up" position of the moustache bars.

On the way back (with an incredible wind behind me), I flew back, sitting much higher. That was an incredible feeling - to go 42 miles with a 15-20mph wind at your back!!! I remember going 23.5 mph at one point, and not feeling any headwind, not hearing any wind sound. I maxed at 52mph on a descent, feeling very steady and comfy on the Moulton's long and suspended wheelbase.

The Capreo (9-26t cog, with 53/39 front rings) is wonderfully suited for Moulton's 20" wheels. I stayed in the big ring most of the time given the wide 9-26 range. The low gears were ideal for the moderate climbing on this route. (Loves my derailleurs!)

All in all, a wonderful setup, and I'm very glad to have made the change.

Oh, and some bonus scenery from the ride:
