395.1 | Super-recumbent | EUCLID::PAULHUS | Chris @ MLO 8-3/T13 dtn 223-6871 | Mon Jul 20 1987 11:59 | 5 |
| My 'dream bike' would be a low-handlebar recumbent with a high
bottom bracket (for best use of leg power), a light partial fairing,
and a super-flywheel that would absorb power when braking and help
in climbing hills. Then I would have safety, comfort, speed, and
hill-climbing ability. What more could you ask of a bike? - Chris

Is this a 2 wheeler, or a 3 wheeler? I imagine that it would be hard to lean
on a bike with a flywheel.
Perhaps you need to put a second counter-rotating flywheel right next to it.

395.4 | Italian High Tech | BPOV09::ERICKSON | | Tue Jul 21 1987 12:49 | 25 |
| My dream bike is the Modolo Kronotech, designed by Domenico Modolo.
This is the high-tech bike you've probably seen in some bike mags,
like Winning. A poster-sized photo/tech description graces my office
wall:
WHEELS: Integral carbon-honeycomb. 28" rear, 24" front.
FRAME: monobloc, carbon-honeycomb hot cast in autoclave.
FORK: Carbon-Ergal
HANDLEBARS: Carbon-technopolymer, aerodynamic w/built-in
computer (which looks like a Cateye!!)
CENTRAL MOVEMENT: Ergal-titanium
Total weight: 8.5 Kilograms
This bike is essentially a wickedly high-tech time-trial bike.
Everything is aerodynamic; the styling of the frame (more of
a chassis, really) is susceptable to cross winds, however.
Someday when I win Megabucks I'll get this! 8^)

I would like a real_cheap_bike. I would like everyone else
to have real_cheap_bikes too. I would like us all to ride them
wherever we are going and park them there (neatly) for others to ride
somewhere else. I would like there to be a fleet of communal property
bikes. I would like them to be very light, say 15 lbs, to be totally
maintenance free and to afford total weather protection, yes, *TOTAL*.
I would like the efficiency to be adjustable from high for
transportation, to low for rigorous exercise. I would like the design
to fit everyone's size and proportions, or to be self adjusting (we got
compooter chips, ain't we ?). I would like these bicycles to radiate
peace and friendliness to all other road users, I would like all
vehicles and all road users to do this.

While in Goodale's last year, on of the fellas showed my a bike
(can't remember what it was, help!) that had a either an ultra-light
aluminum or poly-carbon based frame that was held together by some
fairly aggressive allen bolts. Thats right! The frame was made of
components which could be taken out and replaced with new ones to
get back that ol' new bike frame responsiveness.
Or, a nice enclosed and highly visable (but not pricey like the
Vector) recumbant. The flywheel sounds great, but it has been
experimented with. In order for the flywheel to make a difference
it must be of some substantial weight, and the gyroscopic tendencies
of rotating flywheels (read: when spinning, they like to stay in
the same plane and can exert tremendous force to do so!) made the
experimental bikes go great guns, but only in a straight line. I
remember two scenes from a film, one of such a recumbant approaching
the first curve of the track and gliding gracefully into the wall
(keerasssh!) and another of a complex cermaic based flywheel exploding
while in mid flight and desecrating the bikes outer shell from within!
Anyway, anybody know what the frame in paragraph 1 was??

re: .5
Reg_B, you've got it! I agree completely.One that will
S T R E T C H out and grow an extra seat when you feel like
company.....one that'll prevent any shifting when you want to do
a "Reg climbing Mt. Whatsis" imitation, etc etc etc.
right on, ol' chap!!!!

395.8 | More than a dream... | KIRK::JOHNSON | Matt Johnson | Wed Jul 22 1987 14:56 | 17 |
| RE .5
When I visited my brother at the University of Michigan, I spotted
a battered bike painted lime green with a sign on it. My brother
explained that it was one of the famous "green bikes," which are
free for anyone on the campus to use. People grab a free bike,
ride it to their destination, and leave it there for anyone else
to use.
The original bikes were found and never claimed, or donated.
The program is less popular now than in the 'seventies, so the
bikes are something of a rarity. My brother felt lucky to be
able to ride one the day was out there, because he didn't get
many chances. Still, it's a continuing, nobel experiment in
community ownership of transportation.

395.9 | My dream bike | IAMOK::WESTER | | Wed May 17 1989 15:36 | 26 |
| I stumbled across this note and decided to add my .02 on what I
would choose as the ultimate bike.
Frame would be either a Serotta Colorado or A Merckx, no composites
or aluminum. It will be racing geometry but allow no hands riding
and have a forgiving ride while still being as stiff as anything
(wow, this really is a dream bike!).
Components? a mix, and because this is a dream bike it will all
work togther. Dura Ace 7 speed cassette rear der., Dura Ace front
Der., Mavic shift levers (the ones that are hollow) C-record Crankset
(a thing of beauty) and bottom bracket. C-record Delta brakes,
C-record hubs and headset (aren't hubs and headsets really where
Campy stands above the crowd?). And, of course, the C-record aero
seatpost. No dream bike is complete without it!
Wheels? A pair of the lightest clincher rims, and a pair of the
lightest tubular rims too. 32 spokes, C-record hubs, double butted
spokes. Tires, Specialized Turbo VR's, Vittoria seta CX's (?).
Pedals will be the shimano clipless ones.
Color of bike? A nice blue,red fade that will match the new Digital
bike Jersey!
Did I miss anything?

395.10 | For those of you who like LIGHT bikes | CESARE::JOHNSON | Truth is stranger than fiction | Mon May 22 1989 09:18 | 23 |
| I met a guy at a criterium Saturday who had a Riva Trecia. This bike
is made out of titanium. It has a one-piece titanium stem/handlebar,
titanium crankshaft and quick-release hubs, and titanium
who-knows-what-else. It weighs 7 kilos (15.4 pounds), complete. They
guy wouldn't admit how much it cost, though I've heard that the
titanium is so expensive that you get charged by the frame size -- the
bigger you are, the more your bike costs.
On the home front, I've decided to be a total hypocrite and blow a
bunch of cash on a "dream" bike. It will be a custom-made Sannino with
Columbus Multishape tubing, Dura Ace 8-speed drivetrain, and Campy
Record Delta brakes. (I'm not going with the C-Record crankset
because I want to be able to swap chainrings with my current bike.)
It won't be especially light, but it'll be the ideal bulletproof
racing bike for me.

RE: .9
Unfortunately, you can't use C-Record hubs with Shimano 8-speed.
I wanted to!

A friend of a friend I know has been consulting to the Merlin company
- I think they are located somewhere her in Mass - for the production
of their Titanium bike frames. Merlin markets these frames under
the Merlin name and also under the Kellogg name. I think the Teladyne
company has also been making some Titanium frames. Just for trivia,
a company called Speedwell was making Titanium frames in Britain
in teh early '70s.
Anyway, you can get a Titanium frame for under $1000 from Merlin.
They really aren't much more expensive than an Eddy Mercx or a Colnago.
I don't know if you get charged by the amount of Titanium used or
not.
I don't know much about these titanium components beyond the fact
that Campy uses titanium pins in all their C-Record stuff. And
I think that Zeus makes a titanium bottom bracket.
And for all you lightweight junkies, since the titanium is a
non-corrosive metal, it doesn't need to be painted. So you can
save a couple of grams by not painting it.
