From Spencer's Bloghttp://snwright.blogspot.com/2007/04/chupacabra.html
I am pleased to introduce to you the Chupacabra, a staggering creation from Traffic Cycle Design, LLC
Designed in coordination with Goat (David Yost) of the Riding the Spine
tour, this beast has been tailored for long-distance mountain riding.
It sports a stout, stiff geometry, 26" x 4" tires (with an actual
diameter of 29") , disc brakes, and an internally geared rear hub. It
is also compatible with the rack system made by Xtracycle, allowing its
rider to carry loads in the hundreds of pounds.
It's not your
everyday bike, but my opinions of it have improved significantly since
I started the project. Not only would I insist on a similar steed if I
were embarking on a long mountain ride, but a slimmed-down version
would be excellent for doing errands around town. It could carry all
the groceries you'd need for a week, and could also be outfitted with a
child (or spouse) seat.
What's with the name, you say? Wikipedia has a decent article
on the chupacabra, a little creature known in the Americas for killing
and drinking the blood of farm animals, especially goats. With the size
and mass of this vehicle, I expect it to have a similar (although more
invigorating) effect on my friend Goat.
