    Hey - I want to be able to ride this in the PBP, and also in gnarly singetrack. Why don't the tires
    have both capabilities?

    Why stop there? Make the front a TA Cyclotouriste quad, and add in the Swiss bottom bracket
    two-speed planetary gear system (available form Harris Cyclery, natch). That'll give him 112 speeds.

    Of course, with the front chainrings he'll need a device to take up chain slack. So, why not add a
    cassette of some suitable size (Campy 10 speed?) Then he'll have 1120 speeds! Talk about overlap!

    Yes...Lost it....Looks like a tandem for siamese twins!

    So _that's_ who test-rides it, Sheldon together with Carapace Umber!

    Sheldon, you're missing two types of bells. Maybe a bell on one handlebar and a horn on the other,
    to warn others of your approach.

    And by that time you wouldn't be able to pedal the 80-pound monstrosity because drag would be so
    high, lol.

    Triathletes sometimes control one brake from two levers using a splitter:
    tri-zone.comBrakeLevers.html Brake Splitter

    2 sets of brake levers are sometimes used in 'cross, too - those in the conventional position, and a
    pair of flat-bar levers on the straight top section of the drop bars. Simon Burney's excellent book
    "Cyclo-cross: Training and Techniques" gives an outline of how it's all set up.

  9. Clearly, his creation needs a Schlumpf drive to be complete.

    I knew someone with that same dual handlebar setup back in the 1980s.

    Sheldon - how did you get two sets of brake cables to connect to the same brake? How does that
    work? - If successfull you could have a good invention for tandem stokers to use.

    Hmm, what kind of drugs have you been taking? The LAST thing I want a stoker to have is a set of
    brakes. I'll give 'er a bell and a horn if she needs something to do.

    Tanden shmandem! Could you imagine how popular this would be with cyclists who use aero bars?
    MTB'ers with bar ends?

    May you have the wind at your back. And a really low gear for the hills! Chris

    And if so, how does it manage to fit into that tiny space? I've serviced Sturmey Archer 3speeds a
    few times, and while those are certainly pretty heavy on the big & indestructible, 2 planetary gear
    systems in a BB is just mindblowing..

    Some BB gear trains such as the old Dana unit hang over the right side of the BB shell and are quite
    a bit larger diameter than an AW hub. I haven't seen the Shimano unit but I'll assume it is
    similarly built.

    now THAT is scary. Looks like it might break in half on the first bump... and a quick dismount
    looks like it might be a trick... and looking at where that chain passes, he'd better keep that
    zipper up - Ъ×

    He sent me a three/four minute videotape; it was interesting to see but even from the still photos
    you can appreciate he may have trouble mastering right-hand turns, I feel....

  17. keep doing stuff like that and you'll ruin the spine!

  18. i wuza just in the shop looking for that rohloff stuff with an enclosed disk brake attachable so i
    copied the litany and will check it out. know the DAF? made in the netherlands and may still be if
    not flooded. i don't know how but assume that someone has thought up a way to dial in patent groups
    and research the subject just so like googling but maybe that costs. the friction loss is off course
    a killer but the idea is stimulating
