max trike speed?

[DD]

Just about finished making a tailbox and will be trying this out by
coasting down a long hill several times with and without to see the
effect (and of course if it doesn't just fold up under wind pressure).
The max speed that I have been down this hill by means of a roadbike at
max rpm and tucked down Tour de France-style, by Greenspeed GTR trike
and a massive gear, by trike with front fairing and no pedalling, is all
85km or so. We are talking of a 2km staight run.
What sort of speeds have others done?
We have gone for the outsized tailbox, that is slightly wider than the
rider in profile. Bigger as better. Any opinions on tailbox shape and size?


(Note that I am not trying to brag about speeds or even promulgate the
idea that trikers are downhill freaks, to promote unsafe road behaviours
or various other anti-social charges that you may think to throw back at
me, I just want some comparisions. Probably a bit easier than fitting
the trike in the local uni's wind tunnel.)

Andy Wilkinson was allegedly clocked at around 70 mph on big descents on
his record breaking Lands End to John o'Groats run on a fully faired
Windcheetah. Even if I was physically capable of that sort of speed I
doubt if I'd be psychologically up to it without suffering from
excessive Heebie Jeebies...

I didn't mention that my trike has drum brakes. I don't think, even if I
could do 115km/hr, that I'd want to without a more decent stopping power
like disc brakes.
I have done 85km down my particular hill, cranking a big gear but not
out to full rpms, but enough so that I just about hover above the seat,
something to do with arching muscles and body deciding to act like a
paper airplane and fly away. So at a high enough speed and crank effort
you feel to float while dropping downhill and at great rushing speed. A
three-wheeled magic carpet ride. All the time that bitumen, I know, is a
bit rough and certainly steep enough, like a long strip of sandpaper,
roughest grade. If I came off the trike at that speed it would take a
very long time before I slowed down to a stop. Hamburger anyone? What
would 115km be like, well like you I'll leave that to the imagination.

The common max speed seems to be about 85km so thanks to everyone for
the feedback.

He once told us that he'd been doing 76 mph during his record-breaking
run round the Isle of Man Mountain Circuit, /with the brakes hard on/,
and muttered something to the effect of not having much faith in
Sturmey-Archer drum brakes any more...

Old Andy should join the circus. They have all kinds of crazy people there
who can do all kinds of crazy things. Maybe Andy could ride his bike across
a rope stretched between two poles high above. Then the rest of us dunces
down below could oh! and ah! at the idiotic spectacle of it all.

PS. Anyone here know what a Medical Physics IT Officer is? Peter won't tell
me and I refuse to look it up.

It took us Americans to show the Europeans how to wage a war in Asia.
Afghanistan and Iraq proved to be cake walks for us, but the Brits and the
Russians never could get it right, not even in colonial times when the
natives were weak as kittens. But tiny Britain sure does know how to handle
mighty Argentina. They proved that in the Falklands War.

America is the New Rome. We mean to kick some ass, maybe even European ass
before we are done.

I know, but I refuse to tell you. It seems as if everyone else is also
refusing to tell you. So if you are too lazy to click the above link and go
to the guy's website, where he clearly describes his work (this would take
about two minutes of your time), then I suggest you stop wondering about his
employment forever. On the other hand, if you simply can't let go of this,
then you will have to beg me to tell you; I mean really get down and grovel,
and only then might I relent and explain it to you out the goodness that
resides in my generous heart.

So what say you Mr. Dolan?

As an acronym, ASS should be in all capital letters.

The general trend is for European Above Seat Steering (ASS) is for "C"
bars while the US preference has been for either "T" bars or "ape
hanger" bars. However, there are some notable exceptions, e.g. the
Benelux manufacturers seem partial to "T" bars while highracers from US
based companies usually have "C" bars.

As long as Dave Larrington of the UK posts his idiotic signatures reeking of
liberal politics, he will get a little rejoinder from me. Get used to it.

I could care less what a Medical Physics IT Officer is or does. Screw him
and his idiotic signature! What I am objecting to is his signature - period.
It is long winded and tells us more than we would ever want to know about
him. It is like he is advertising himself to this group of recumbent
cyclists, and for what purpose? No one else on the group does what he does
in regard to a signature.

Peter Clinch is an ego maniac but I am letting him know in my own inimitable
way that I am a greater ego maniac than he is. Surely that is fair. But he
is a coward and has kill filed me so that only you and I are paying any
attention to this folderol. However, he will see your response to my message
and so that will alert him that I am not yet done with this fool from the
UK.
