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?

He has 14 speeds now. Add a triple and that would give him 42 speeds!

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!

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.

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.

Is this a bottom bracket thing?

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

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

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....
 
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
