27 MPH, what's this all about?

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Here's one more reason not to worry. I've started riding again, in a very hilly area, where it is a struggle (some of the climbs are 3/4 to a mile and a few have true wall status) to "average" 16 MPH for 40 miles. The other day I was waiting on somebody at lunch so I took a spin from my office on a loop that included only one false flat and was amazed when I got back to see that I had averaged 19 MPH just kind of cruising in the 42...and like a light bulb it came back to me that the hills kill your average speed way more than the downhills help...going straight up at 10 MPH for minutes at a time really has an effect. So average speed is only one thing to look at...I was told by a top racer that your high end flatland speed it a better reflection of what you could do if you trained for racing...I could crank it up to about 29 at that time (33 now) and hold that for about 1 mile...he said that meant I should have no trouble holding 25-27 in a pack and that was pretty much true...could cruise at those speeds in races. He had a top end speed of 36 MPH on flats...and he was the kind of guy who could win a solo breakaway...

depends on how you look at it. if the computer is reading the same RPM for a larger wheel size (easy to change the settings), then you'll be increasing the speed - according to the computer. if the computer is reading the same RPM for a smaller wheel, then you'll be decreasing the speed - according to the computer.

EDIT - i was actually referring to artifically changing the wheel size in the computer (making it larger) - which is basically the same as physcially putting on a smaller wheel.

quick question from the new guy...for those of you with mountain bikes too, what types of average speeds do you post on your mtn compared to you road? I am curious to see the difference one type of bike makes towards the other. Reason I am asking is I do all my riding now on and Alum MTB and soon will be acquiring a descent road bike. I am wondering how much my avg speed will jump up on the new rig. Right now I get only about 15 to 16 mph with my 2.10" hoops...always riding on the large chainring(which is only like a 43 ot 44 tooth anyways)

I noticed a big difference. Can't say exactly how much, however I know I was getting into work a lot quicker. I'm not sure if thats a good thing.....

g'day,

27mph/43kph....wheew, you seppo's are too good for me...i'd have to change to the big chainring to average that for more than a few minutes!. There's an Aussie term to describe those riders (ammo's), that reckon they can pull 27mph all day......."bull**** artists"

cheers,

Hitchy

You guys are my motivation. I've been road biking for a little over a week now, and I can only average about 15 miles an hour on my 20 mile rides, I could not imagine averaging 27 on an even longer ride.

I for one don't claim to average it for the ride, But I am able to do it for several minutes when it matters.

I buy that...but haven't you, just once, maybe twice, averaged 28 or 26? LOL.

Could 27 be the Bike Forums equivalent of Spinal Tap's 11? Just a thought.

Yeah man! We clock our speed at 27mph not 26 like other forums. Because we're faster then everyone else!

Ha, I just looked back and I may have been one of those "magic" 27 posts. Someone described a 3 mile TT classification, so I found the flattest 3 miles on my commute and gave it a shot (panniers and all ). I recorded 6:40, or 27mph average.

But, I should add, that I suspected that it may be a slight downgrade, so I tried it again on the return trip, and recorded 8:00, or 22.5mph average.

So really, 27 may just be everyone's favorite number to toss into a conversation...when they see that on the speedo, they feel obliged to mention it

I checked my strava log from yesterday. I was over 25MPH for about 3 miles and apparently maxed out at 30.2 MPH. This was the last sprint of the day and I was gassed enough that I didn't do any interval work today.

So, saying that I can do 27 is true, and deeply misleading.

I am dying to know the sequence of events that led to you finding and responding to this 14-year-old thread.

I'm not even being sarcastic, was it a google search result or something?

Wow, did bike forum members get a lot slower in the last 14 years...

No longer talking about 27... it is now 20+ Commutes.

Of course, Lance Armstrong was racing until 2005... perhaps all the Bike Forum members of that era were also on EPO and steroids.

In the mean time Strava, GPS computers and power meters was invented and adopted by everyone (mostly). These days arm chair racing is a lot harder to get away with. "strava or it didnt happen" and all that.

Yes, but with all the global warming talk, I thought we were getting more wind.

Speedometers were common a few decades ago, but there certainly is a difference between instantaneous speed and average speed.
