Sturmey Archer S2C Review

The Sturmey Archer 2 speed, coaster brake hub, as fitted to the Moulton TSR 2, is reviewed in the current issue of Velovision (Issue 40).

The reviewer tested the old F&S Duomatic hub alongside the new Sturmey S2C for a better comparison between the two hubs. Some of the main findings were:

  • The S2C is about 50% heavier than the Duomatic
  • gear ratios are identical
  • the S2C requires less of a back-pedaling action in order to change gears
  • the brake on the S2C is much stronger

The review is very positive, and the main benefits cited are that you get the simplicity of a fixed gear with a "bailout" gear for hills and headwinds, as well as the lack of cables going to the rear, which is particularly useful for separable Moultons.

Issue 40 also includes an article by Moultoneers Keith Hales, where he describes life with a Double Pylon, and includes his visit to the 2009 Moulton Summit in Japan.

Moulton TSR 2

The Moulton TSR 2 Specification has been released. This model features a 2 speed Sturmey Archer S2C hub, with kick-back shifting and a coaster (or back pedal-) brake. This means that there are no cables running to the rear wheel, and allows the frame to be split more quickly for storage and transportation.

The initial prototypes, which were shown last year, featured a belt drive, eliminating the maintenance and dirt associated with chain drives.

However, the production TSR 2 is available with a choice of either belt drive or a standard chain drive. The belt drive model features a Delta 11mm belt, 67 tooth chainring and 25 tooth sprocket, providing approximately 50.6 and 69.9 inches.

The chain drive features a 44 tooth chainring and 17 tooth sprocket, giving gears of approximately 48.9 inches and 67.5 inches.

The TSR 2 weights 12kgs, and also features folding pedals and Avid Single Digit 5 front V-brakes.

The Moulton Bicycle Company Website says

Beautiful simplicity - the TSR 2 features the new Sturmey-Archer 'kick-shift' two-speed gear with an integrated back-pedal brake, and belt-drive. Two well-spaced ratios keep you moving through city streets - no shifters, no cable, no adjustment.

Moulton Bicycles at Cycle Show 2010

The Moulton stand at Cycle 2010 had a stunning stand, as usual, with some new innovations on show.

This New Series looks interesting. It is the first factory built Moulton to be fitted with a Rohloff Speedhub.
Unlike previous standard New Series models, it features the Flexitor/front fork design from the Double Pylon. The front forks run entirely outside the front flexitor assembly, rather than passing through it in the style of the older New Series models.

The flexitor pivot assemblies are redesigned featuring a narrower middle section on the two side tubes, rather like a double-butted spoke. It also doesn't appear to have a soft lock-out mechanism.

The New Series also features a threadless headset and a new variation of the Moulton Wishbone stem.

The demo model has wide Continental City Contact tyres. Up to now, the NS tyre clearances were too small for all but the skinniest of available tyres. Tyre clearance is helped by the use of longer reach dual pivot brakes, which may be a custom Moulton item.

There was of course the shiny belt-drive TSR-2 with 2 speed, Sturmey Archer S2C kickback hub.

And it was nice to see the beautiful original chrome S Deluxe, owned by Mike Woolf of Moulton Preservation on show.

Two Little Wheels to Paris

Andy Morris is riding from London to Paris, on a Moulton TSR, to raise money for the Alzheimer's Society.

In September 2010 I will be riding 300 miles from London to Paris to raise money for the Alzheimer's Society. But things are never that straight forward - I will be riding my distinctive Moulton bicycle, immediately recognizable by its little wheels.Genius or lunacy? Stick around and find out. Follow my vlogs as I train and participate in this event.Donations large or small to the Alzheimers Society are all gratefully received, just use the address at the end of the video.Thank you for your support.

He has produced some cool videos showing the Moulton in all it's glory, including "It's not about the bike" shown below.

Follow Andy's ride on Facebook page, or on the Vimeo channel. You can donate to a worthy cause at http://www.justgiving.com/A-J-Morris
