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!

G'day,

that's it MTB 'ers cruising at 40kph!....now i know what I've been doing wrong all these years...wasting my money on lightweight high end road components!!!!....thankfully you blokes have helped me see the error of my ways before I 'blew' anymore cash in the pursuit of speed. I'm going home & put the 'roadie' out for the hard rubish collection tomorrow....& getting me an MTB!......BTW, I've emailed this thread to Lance....looking forward to seeing his MTB rig at this years TDF,

cheers,

Hitchy

Hey, don't let them get to you. There's help at hand for speed addicts, such as yourself. Buy a fully fared recumbent. :D

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

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!!

But what a hollow unfulfilling exercise. Enjoying the spoils of descending without the pain

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 the power requirement increases as the cube of speed, because power is the rate of doing work. So there is a big difference in power required to reach 50 km/h compared with 40 km/h.

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

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

He must be talking 40-50 metres an hour? How did this get to aus.cars anyway!?

Yeah, I got nice and close with my camera after the final Bay Series crit this year. :)

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 retchford or Mark_Pringle So I am not sure which "******" he is talking
about ;) lol stu
p.s. maybe if you got some more gears you could go faster hippy 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.

>I'm only in C. Many conditions could work against him - he's not a jack-of-all-trades.

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).

>I could beat him too, perhaps, if he'd just finished a 250k late-stage of the tour, with a sprint

Make sure it's a downhill finish. Gravity works :)

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 news reader attributes it to you. Perhaps your quoting of others was too 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 Groups your word is intact, but not when I look with Cycling Forums, who must feel that such basic functions are not fit for my eyes and my unedited reply not fit for yours. You will probably find it altered again in this reply.

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