How often can you sustain 40kph around the city though?
Do you stop at lights, dodge cars, dodge peds, stop for
trams, etc? My commute is in traffic but the roads are
straight and there are a few hills, but my avg. speed never
got anywhere near 40kph. Maybe if I took the fastest
10k section I could get to a 40kph average speed, but
that's almost half the ride so it's unlikely.

Best riders in the world on totally aero TT bikes, with
all manner of coaching, training, natural ability and chemical
enhancements behind them. That's a little bit different from
your average aus.bicycle poster (I'm guessing) who is riding
around the city on an mtb.
I don't claim to be super fast, but I seem to pass an awful
lot of people when I ride and you are putting my speeds to
shame! ;-)

You're confusing average speed with cruising speed, when they are totally
different things :)

Average speed = Distance/Time.
Cruising speed = a rider's sustainable top speed.

BTW, if you read my post again, you'll see that I never claimed to cruise at
40km/h all the time... the instance quoted with a 40km/h speed was with a
tail wind, which I happily confessed in my post. In the same post I said
that normally I cruise at about 35km/h. I recently callibrated my computer
over a known distance of 5km, and it was only a hundred metres off (i.e. 2%
margin of error).

My cruising speed of 35km/h vs David Millar's at 54km/h seems like a pretty
big differential to me. To give another perspective, there was the time
before Xmas last year when I was passed by Robbie McEwen who was on a
training ride in inner Melbourne (he was wearing his Aust champion/Lotto
Domo jersey, which is how I knew it was him). I kept up with him for less
than 1km (with my speedo reading... yes... 35km/h), before he obviously
decided that he was going to get serious. When he put the foot down he blew
me off so quickly that it was laughable. In the space of 15 seconds or so he
put about 100m distance between us. It just shows how much better those guys
(& their equipment) are than mere mortals like us.

Ahh not this again... I did the same thing to amirm! :)

Okay, even though I picture "cruising" as someone idling along,
looking at the scenery.. nothing near max :)
It's still a vague definition - "sustainable over what distance?" makes
it quite variable.. i.e. your 100k reference

I just don't see many oppurtunities for doing 40kph for more
than a block in the city. I've got to get back to work on the
"Make Traffic Lights Go Green Now" machine for my commutes
and see what times I can get ;-)

That's cool! I'd love to race Robbie! Even if it was for only 15secs!

Don't bother trying to draught behind him. He's not exactly a big guy
:)

BTW, there are guys racing at Glenvale who have beaten him.

About time you saw the light. Dont let that slow old roadie stay in your
house another day. Tell you what, l'll come and pick it up, just so you
arent tempted to ride it again.

Hey,

Why not try plastic surgery. Leg transplants do wonders ya know. Longer legs
= faster revolutions!!

If that doesn't work just buy a rocket pack!

By now!!

Get real. I was unfit at the time and managed 40 to 50 on the flat
with a 12-speed Malvern Star made from heavy steel, running shitty
tyres, and carrying 20kg or books and paraphenalia. Hardly breaking
a sweat.

I am very real and this does not always sit well on forums like this
where some contributors are prone to exaggeration

The major retarding force on a bicyclist is due to aerodynamic drag
Aerodynamic drag increases as the square of the speed and hence th
power requirement increases as the cube of speed, because power is th
rate of doing work. So there is a big difference in power required t
reach 50 km/h compared with 40 km/h

I estimate that 400 watts is required in your case to reach 40 km/h an
700 for 50. Many good triathletes can produce 400 watts for a reasonabl
period of time, but they are fit, near to their limit, have good tyres
don't carry books (time trial instruction manuals perhaps?) an
certainly sweat a lot. They are not "cruising". None of these people ca
produce 700 watts for more than a very short time

Please buy some new tyres, leave your books at home and cruise som
more. Let this group and the AIS know how you get on

He must be talking 40-50 metres an hour?

A-graders though, right? I'm only in C. Many conditions could
work against him - he's not a jack-of-all-trades. I could beat
him too, perhaps, if he'd just finished a 250k late-stage of the
tour, with a sprint and I was fresh.. maybe.. ;-)

I dont think this thread did. Maybe he is talking about the thread "Re: It
was bound to happen" starting on 9/02/2004, but be warned its longgggggg.
I havent got down to DRS's posts yet and I cant find a post by you, john

So I am not sure which "******" he is talking about ;) lol

I didn't go this year. Injured and unable to stand up for extended
periods. I went to Buninyong for the mens' RR though. Well worth it. A
great day out.

When you watch them on TV you don't really appreciate how skinny they
are.

Yeah. Hilton Clarke and Robert Tighello for two.

Hilton Clarke beat him (and all the other pros who were there) in a
race he really wanted to win (big prize money). The Launceston Crit in
2002. Will Walker beat him in one of the Bay Series crits last year.
It depends who's the best on the day (and a lot of other things).

First, how about you getting the attributions correct. I never made any
such claim, I was quoting someone else's response to what I wrote and you've
removed the context I provided. He's the ****** in need of a reality check,
not me, and as far as I know he's not even reading this group. And there's
no need for you to edit "shitty".

The "It was bound to happen" thread actually started in aus.cars and part of
it got cross-posted here but that sub-thread died a natural death. It's
still going strong in aus.cars, even though I've conclusively proved that
there is no direct link between rego and road funding, that road funding
comes from consolidated revenue and that therefore cyclists do contribute to
roads by virtue of paying the same taxes as everybody else. A couple of
diehard wankers, including the idiot I quoted to show you lot what a joke he
is, are now trying to claim the cyclists are freeloaders because twelve year
olds aren't made to get licences to ride their unregistered bikes on the
road.

1. If you did not write the quoted material, I apologise. My new
reader attributes it to you. Perhaps your quoting of others was to
subtle for me

2. I did not edit your good Saxon word. That was done by Cycling Forums
through which I posted. When I look at your post with Google Group
your word is intact, but not when I look with Cycling Forums, wh
must feel that such basic functions are not fit for my eyes and m
unedited reply not fit for yours. You will probably find it altere
again in this reply

I gather now that we were both mocking the same original exaggerator
