What's your top speed for flat road?

[screenman]

There is a very easy way of increasing the reading on your speedo for those that would like higher numbers. Just put two magnets on the wheel, simples.

 

[HovR]

There's a ford Sierra still running?

I know of a guy who has a regular Sierra, and a nice looking Cosworth Sierra - Both running by the looks of it, although the Cosworth is kept on axle stands with the wheels hidden away until he uses it!

 

[MattHB]

I had a brown Sierra. It caught fire in a cinema car park because I left the oil filler cap off!

 

[SquareDaff]

29.6mph over a sustained distance, flat and no wind to assist/retard. That's with significant effort. Cruising is around 23-24mph (on the road bike)

 

[TheLondonCyclist]

Are you on road bikes when doing these speeds?

Yes.

 

[postman]

Top 24mph mind you it only lasts a few hundred yards.

 

[Rickshaw Phil]

My best was 28.5 mph over 1.5 miles while slipstreaming a lorry. Normally on a dead flat road it's 15 to 20mph depending on how energetic I feel.

 

[tadpole]

19.1mph average on a 1.25 mile segment (1.2% slope /80ft climb overall). (Don’t do flat sections on my commute)

 

[Scruffmonster]

32mph and I happily cruise for periods at 21mph.

 

[Paulus]

On a good road surface i can hold 18/19 mph. On a sprint I have passed the signpost into Barnet at 31mph, but I did need a rest after that.

You get lots of willy waving on questions like this. I am not suggesting anyone is on this thread, but to get a good feel for how fast people ride take a look at Strava. It gives the elevation at the bottom of the page. Even a couple of % downhill will make a big difference to your speed as will a tail wind, riding in a group and proximity to other faster moving vehicles.

And, just to prove it...

About 160, but I can only do that for 30 minutes before I need to stop for fuel.

Or...

About 35, and I'm sure that the road is flat, although I can only do 12 going the other way when it is equally flat.

Or...

About 5mph, but that's more a ploughed field than a road.

Or... well, a few other examples (wind assistance, starting etc) have appeared on the thread to show what a bizarre and ultimately fruitless question it is.

 

[Pat "5mph"]

Were you drafting behind Doug?

Auch: RM, now all will know about it!

 

[totallyfixed]

How about, how long can you maintain an average speed of over say, 20mph in variable wind conditions and on a not very flat surface? I thought this might be a bit more objective, I could be wrong, I frequently am according to swmbo

I like those kind of flat roads
