The new Esprit was finally unveiled to the MBC, and there were no major surprises.

Most of it was reported previously here on Moultonbuzz, so much of the following is a recap:
- It is lighter than previous AM models, due to the lighter Kasei tubing. It has the narrowest tubing of any non-stainless steel AM.
- It is stiffer than older AM models due to a slightly wider construction.
- Hairpin construction (as on the ATB and APB), where the narrow tubes wrap around the headtube and seattube.
- The Esprit will be available in a variety of headtube lengths and seat tube lengths, and a choice of either standard (27.2mm) seat post diameter, or the larger diameter Moulton 31.4mm seat post.
- Choice of headsets – threaded for quill stems, threadless / Ahead or the Moulton wishbone as per the New Series.
- The separable model looks quite familiar, but the fixed frame model has a straight bottom tube, similar to the TSR / FX8 / Pylon, etc. Shaun indicated to me that the separable model is more torsionally stiff (due to the angled bottom tube).
- The wishbone stem is now available in black.
- Frame skins are available, so you can dress your bike, and change it’s dress if you don’t like it! Alex Moulton’s words, not mine!
- The HED wheels weigh only 2 ozs (which is about 50g) more than a standard wheel.
- The Esprit will be available as a frameset at around £1200.
- Three grades of front suspension are available: soft, medium and hard. The hard is equivalent to a New Series with the soft lockout engaged.
- A number of racks will be available – if I remember correctly a large platform rack, a day rack and a front rack. The existing AM racks will not fit due to the hairpin construction.
- The “standard” colour is a the commonly photographed grey, but a choice of colours will be available.
- Orders are being taken now, and they expect to deliver in around 2-3 months. New manufacturing capacity has been added to facilitate the Esprit, so that Esprit production won’t impact on New Series production.
Alex Moulton said that he was pleased that the availability of HED wheels and frame skins would improve the aerodynamics of the bike.

Shaun mentioned that the reason for the revamped AM was a request from several overseas Moulton distributors. I can guess that these are Japan, Germany and possibly Switzerland. This seems to indicate that the AM is still very popular in these areas, perhaps more so than in Britain.
Three demo bikes were available for testing, and I had a go on all three around the new test track.One demo had the wishbone stem and Mosquito bars. Shifting was via a Shimano Dura-Ace 9 speed
One of the New Series demo bikes was set up with flat bars, but with a slight angle backwards and felt like a perfect setup for town. Though in what town could you lock up a New Series!
The test track is quite lovely – every garden should have one. There are a number of short sharp inclines and declines, and tight corners. Though a bike cannot be fully evaluated on a short test track, it does give plenty of opportunity to see how a bike feels climbing, descending and handling in tight spaces.

Nit pick: The TSR 27 has regular 40-406 Marathons. The only (35-406) Marathon Pluses were on my bike

Thanks for the correction, Chris.

Another correction, the “bar end” shifters on the Mostuito bars are actually indexed down tube levers, mounted on the bars, so they’re used like a thumb shifer
