Riding thru corners

[cnighbor1]

Coming down Mt. Diablo, CA on my Paul Taylor road bicycletoday I took has usual all the cornersby approaching from the outside of the curve to the inside of the yellow line and back to the outside. Just like the Pro's on the tour de france. than think back to my physcis classes in the 50's I can't see the advantage. If I stay on the outside of curve I would travel a longer distance and radius of the curve would be greater and a bit safer. This would also allow a greater time to brake if needed.
So why do pros ride has I did.

You go faster if you're doing it right.

Going outside-inside-outside is the greatest radius you can take.

Yes.

As you can see from this diagram, the "outside-inside-outside" arc has a larger radius than following the outside of the curve:

The larger radius requires less centripetal force (i.e. cornering traction) for any given speed.

[cid499]

"When analyzing a single corner, the optimum line is one that minimizes the time spent in the corner and maximizes the overall speed (of the vehicle) through the corner. If one used the path with the smallest radius, that would minimize the distance taken around that corner. However, by fitting a curve with the widest possible radius into the corner, the higher speed which can be maintained more than compensates for the extra distance travelled."

(http://en.wikipedia.org/wiki/Racing_line)

tl;dr - Taking the route with a larger radius lets you go faster while maintaining traction and results in a shorter time

Ah I shouldn't have thougth of that,at home. going 22 mph down hill leaves little time to picture your great drawing in my mind
Charles an an architect at that

When I go downhill on Mt D. I go so slow that I can do inside to inside to inside. Much safer. :eek:

Sorry to get a little off topic, but you need to do some spell and or grammar check on your comments. You have to pretty much guess what you are talking about "as written". Looks like most people got it but still.Coming down Mt.

It isn't safer if hugging the inside of corners reduces your line of sight. If you delay your apex until you can see your planned exit point or "trackout" as automobile/motorcycle racers say you can dive for the inside if all is well but you can also continue on the outside line if there is something in the road(car, animal, oil, fallen rocks, etc.) where you thought you would apex. If you are hugging the inside and the turn tightens or there is bad stuff on the pavement you can only try to brake and/or run wide and out of your lane.

Were you avoiding the spiders?

Saw 4 of em riding down Mt. Diablo a couple weeks ago.

On a side note Mt. Diablo is terrifyingly awesome. Here is a great view. http://www.youtube.com/watch?v=BS9fPZG0rPw

Correct......the ideal outside inside outside is hard to make happen on an open road or in a race with a full pack. If you really want to learn to corner start racing crit's and follow a good wheel. It's easy to make up five or more places in a corner. Places that would cost you much more energy on the straightaways!
Apologies in advance to martinrjensen for bad grammar.
