Road Cycling - Dare I say, 60-11?!?!

I did some calculations and at 120 rpms I should be able to achieve a speed on flat ground of 51.4 mph!!!! All I need is a 60 T chain ring. I'll probably throw it on for just a special occassion. It won't be a permanent part of my bike, but will it fit?

Will it actually shift with my stock derailleur or do I need to increase my small ring size to 46?

I'll have to say that you're the strongest and the mightiest cyclist that I've come across on these forums. I can't even push 53-12 at high cadence for any length of time unless I'm going downhill. All the power to ya!

aw god, we got another merton. you need to put out about 2400 watts to go that fast. wind resistance increases with the velocity squared. www.analyticcycling.com

.......I know we shouldn't encourage him any further folks!...but.....I'm prepared to be you can't 'push' 60-11 at 120 cadence for any length of time.....you sure you're feeling alright?...haven't had too much sun, perhaps dehydrated a little much.....why don't you go & have a lie down...you'll feel better tomorrow.....

Hitchy

Even if I can only hit 52 mph for even 10-15 seconds I will be satisfied.

I thought it was just me.....

I dont think you realize how much power 2400 watts is.

...actually...i've calculated, using einsteins theory of relativity.....that if I put on a 4650-11 I can build up enough speed to go back in time & implore 53-11 alltheway's mother, not to do it!

I'll start up a collection for the necessary tools.

That's like 3hp. If you can create the power of three horses pulling dead weight for 15 seconds, "YOU-AH-DA-MAN!!!"

I know a human can produce 1-2hp for very short periods of time, but 3hp?

Holy-smoke-a-roonies!!!

im no physists but you make yourself look silly. and that kinda hurts cause im a gym rat to and you are givin us a bad name

LOL I was thinking the same thing.

Keep in mind that said poster who was thinking of getting such a setup had not even owned a bike at that particular point in time.

Great, you can also tackle the hour record at the same time. All those guys never figured it out - "all they need" is a big chainring.

Why not splurge and push 70T at 125 rpm?

Good luck to you... but just a warning.

I tryed that once, but at a little over 32 mph my pants caught on fire.

.....ahhh, but that's because you didn't have the 'flux capacitator' on the DeLoren adjusted properly.........

I think the capacitor was fluxing but he forgot to put the banana into the fusion tank.

crap. even i ain't that crazy anymore. :eek:

on a recumbent with aero fairings it would work quite well. if you had that one that hit 80.3 mph over 300 meters you could probably cruise at about 50mph pretty comfortably with that 60-11. side wind would knock you over though.

it's trash that goes in the tank!! :D

You are so cool!!!!!!!!!!!!!!!!!!!!
:rolleyes:

Yes, you're a Fred. Ooops, sorry, wrong thread. :rolleyes:

Yes I can pedal 53-11 on flat ground for over 20 minutes (with some minor coasting) at a cadence of 100 to 110.

I think it will be possible to hit the 60-11 gears for 10-15 seconds. It's less than 15% more gearing...what's the big deal?

My legs have the power!!! I can leg press 1100 lbs for eight reps.

I might have to fine tune my aerodynanmics package.

Maybe I'll get some 180mm cranks while I'm at it.

This was not meant to be a joke.

You're saying you can sustain 45mph for nearly half an hour on a road bike, just making sure I'm reading you right.

This was not meant to be a joke.

....we gathered that.....that's why it's so sad for you.....but good news for your psychiatrist!

There's a word for this type of poster..

TROLL

This is the 3rd or 4th thread he's done this is...

But then you'd have to change your username!

Cole

BTW Aren't you the guy that asked about a 12-30 rear cassette? You'll have a hellufatime getting up hills with a 60t

It doesn't work out to 45mph....more like 35 mph.

Seriously people this shouldn't be that hard.

You need:

1. Seriously good tires.....high TPI high psi tubulars will do the trick.

2. 180mm crankarms for increased leverage....may work with my 175mm's.

3. Appropriate gearing....

http://www.sheldonbrown.com/gears/

53x11 @ 120 RPM with 700x20 tires = 45 mph.
60x11 @ 120 RPM with 700x20 tires = 50.9 mph.
60x1 @ 120 RPM with 700x20 tires = 559.9 mph.

Wait wait, let's skip all that and analyze the statement that going from 35mph to 55mph "isn't too hard."

I never said I could push 53-11 for 20 miutes straight a 120 rpm. I said 20 minutes at 100 to 110 rpm (with some mild (5 second) coasting every 2-3 minutes). Anyway 53-11 at 100 rpm is 37.8 mph with 700x25 tire.

Fastest prolouge in Pro cycling history was done by Rik Verbrugghe over 7.6km @ 58.874kmh (36.50mph)

Not only are you faster than Rik Verbrugghe, You can break every single world record on the track and are singlehandedly faster than the Gold Medal winning Australian 4 man team pursuit squad.

Awesome!

going from 37 mph to 52 mph will be hard, but not impossible by any means.

Surely other people have gone this fast?

4 man teams have gone 4km in under 4 minutes, thats over 37.2mph. Thats world record pace.

Petacchi and Cipollini have sprinted for around 200m at 44mph, Marty Nothstein can hit 45mph for maybe 100m You will never hit 52mph, not even 46mph.

If you really want to turn that big 60x11 get behind a van, or SUV and you can do it, but without a draft, and without a tailwind, no chance.

Unless you are something the world has never seen.

THat's it?? What's the fastest top speed through the traps (absolute top speed)?

What is the world record for drafting speed? I heard it was something like 120 miles an hour (behind a car with a special shield set up), but don't know if this is accurate. I imagine you would need an interesting gear combination for that kind of speed.

He probably IS something the world's never seen, but probably not in the way that the cycling world would imagine it to be.

Well, I'm with you, Mr. 53 -- nothing like a bit of confidence -- and I'm a closet grinder, myself. I wish I had such a good reason to get out of bed every day :)

All you need to overcome the thick amosphere is some altitude, maybe 20 miles.

However, if you do manage this great feat, here's all the world records you'll be breaking:

Please note that the fastest ever recorded flying 200m was 9.865 seconds, by Curt Harnett
(CAN, 28.09.1995 BOGOTA, COL), with a speed of 45.361 mph

I hit 40 today behind a cement truck. I was spinning pretty fast, man. lots of fun.

152mph (http://www.canosoarus.com/08LSRbicycle/LSR%20Bike01.htm) (thanks Galen for posting it in another topic) I'm sure 53-11 will be able to hit that no problem :rolleyes:

edit: damn you slvoid

152.2 mph behind a land speed record car.

I've read that book. One of the more interesting things in it is that it took the motor car about 20 years (i think) to match the speed of the fastest tandem bike (~45mph)!!

What is the fastest flying 100 meters? Somebody said only 45 mph.....I seriously think I can beat that. I'm in prime physical shape right now and if I'm going to set a record now is the time.

What kind of equipment were they using?

I'm doing pretty good with just a shimano 105 equipped bike....with better euipment I know I can do it!!!

OK....I've got first dibs on you to be your sponsor. You want your 60 ring?...You've got it!

San Francisco has some incredibly steep hills. THere are older cars that have a hard time going up some of them.

I won't be using a 60T chainring in San Francisco....no way!!!

World classed expensive equipment. I'm sure with some better equipment on a fixie with no loss to the drive train, you'll have no problems reaching 88mph on a perfect surface with no wind. Just remember to set your destination time before you reach that speed.

here's a bit of science to back him up

I didn't read through the whole thing but the words "vacuum velodrome" and "oxygen space suit" were mentioned.

Actually A fixie (single speed) might not be a bad Idea.....That's the most efficient drivetrain out there.

I could probably get by with less gear....such as 55X11 or something like that. Just need to do the calculations.

here are most of the details (gearing, etc) regarding each hour record

I got five on it.
