Unique New Series Moulton
  • Simon 6y

    Mark, that's soooooo cool - got to be the best bicycle ever... New Series frame, Rohloff hub AND a belt drive :-)))
    Did you put it together all yourself? I notice AVC now do a NS with the Rohloff, but perhaps you beat them to it!

    I did. Alex Moulton rode the bike in 2002 and liked the Rohloff. It was destined for production until a visit to Germany 6 months later where not everybody likes Bernd Rohloff. Told that it was unreliable, he backed out which is why it ended up with Richard Grigsby.
    The belt is possible because of the break in the rear triangle that was developed for the Bentley (which used 1/2" tube). The Pylon uses 3/8" tube so this part was sleeved on. You can just see the gnurled screw item in the picture. The front pulley is off a Strida and mated to a 62 teeth Moulton chainwheel (without the teeth). The other vital bit is the "snubber" which hangs off the derailleur mount. This stops the belt teeth from jumping out of the small pulley without adding tension to the belt. Gates' new carbon belts are a huge advance though the 8mm pitch is more suited to 20" wheels.
    After 10,000 miles and a few broken belts, this combination now works rather well. Apart from an annual oil change, it's also pretty maintenance free. Thanks to whoever took the photo at Malvern station. Origami rides are enjoyable whatever you ride!
